Anyone got any advice on a decent cam kit for a 76 302 ? Motor was rebuilt stock . Has a eldebrock performer intake. Holly 600 4 barrel carb . I have a set of gt40p heads and headers . Motor is going in my 66 ford custom 500 4 door car . C4 transmission. Wanna be able to drive it say from Louisiana to Florida if need be . Something that has some rumble and not to terrible on mpg. Thanks in advance
@@pipelinecowboy yeah you probably would need a stall for anything bigger than an HO cam. Here’s an idea you may not love. Put an HO cam in it and on your exhaust run turn downs instead of tailpipes. Then again that may end up being too loud. My white car had turndowns and eventually the novelty wore off and I put tailpipes on…..anywho, I pinned your comment to the top hopefully it’ll get you some better info and ideas👍👍
@@fomobros2207 ok I appreciate it ill look into it for sure. Maybe all I really need . Cause I just want a lil more rumble from stock . I have Flowmaster ready for it also . Just gotta get the cam and time off
Man it was a heck of an experience, I was calling my Dad and brothers every 15 minutes hoping they would have an answer for me lol. Richard came up with the idea to jack the engine up and put 2x4's between the motor mount and k member, I did that, dropped the pan , and that's when I noticed that plug had popped out. I got so dang lucky. Thanks man!
@@vernm6189 I’ll be honest with ya, I changed the cam bc I had some extra money and my idea of adventure is changing cams on a daily driver over a weekend. Obviously that didn’t go to plan thanks to the dang oil plug, but I did get the adventure part in, it just took me a week lol. The cam seems good and it’s tame enough for extended trips on the interstate between 1800-2300. So I definitely like it (but I liked the other cams too). The wrong brother has been doing cam swaps though. Richard would be the best cam reviewer bc he takes his cars to the track. But if you want a tough daily that sounds good then any of the three are great
Nice to see you working on yours, Ray. Been a minute. And this time you worked on it by choice...sometimes a rare luxury, eh? Anxious to hear what you think about the cam after some miles and some high throttle blade angle adventures. I know Richard H. calls it his fave for the smaller cube Fords, and he does enough testing one has to pretty much take his word seriously, even when he touts a CompCams stick. ;)
Haha, only the first part of the job was by choice. Yeah I’ve been putting some miles on it, I took it to the JY yesterdayand fought with some 3 bars for longer than expected. The high throttle blade adventures are soon to follow!!
Face it, people rarely look at OP gauges ALL my hotrods have red oil pressure lights AND 100 db piezio buzzers from "radio shack", hooked to a 15 psi switch. Light comes on, buzzer sounds. Saved me one engine so far. 👍
might want to think about having 2 pumkins a 3.00/3.25 geared for cruising & 3.50/3.73/4.10 gear for at the track. the Comp Cam XE274HR & Valve Springs might help (but what about your Intake VAC?) if you need More Power, add a 75 to 150 shot of NOS. Yes with a Cam change, I'd change to a converter thats Stall street/strip friendly.
I agree about the valve springs. The car is a five speed. I like the idea of a track mode and a hot rod mode. But I think I’ll eventually have two old fords one I can beat on and one to daily. I realized I don’t have the means for one car that can do it all. Thanks
Will do. Fair warning I sometimes work at a snails pace. I really need to get the mechanical advance dialed back on this dizzy (should have taken care of that years ago, like when I had the E cam or the F cam in). But I am feeling motivated to get this thing dialed and I'll let you know.
@@fomobros2207 I just picked up a 93 f150 with a 302. When I get ready to put that cam in what would you suggest on an upgrade for affordable springs? I have picked up an extra set of heads that have been ported and polished but the springs are stock. I'm replacing all the EFI with RPM air gap, 650 Holly. I'm new to this game and I appreciate your knowledge.
John C my apologies for the late reply, somehow I missed this comment til now. I like name brand parts and I’m not very biased either. Which heads are you putting in the car? Are they E7’s or something better? If you look on Summit at the XE274HR cam it shows suggested parts which includes comp can valve springs that are around 80 dollars
I did a little more digging around on Summit and found someone else asked what springs to use. Comp Cams answered with this part number: 987-16. They are 91 bux for just the springs...and it looks like another 50 bux for retainers.
@@fomobros2207 thank you so much. Time that you took to do all that research I really appreciate it. How is your car doing after you put the cam in it were you able to tune it to get more power. Thank you again I'll keep you updated I do enjoy watching your brother on his project motor.
For guys wanting to run the XE274HR on a stock 302 bottom end, check your piston to valve clearance. I put the smaller XE266HR in a stock bottom end 90 HO motor with GT40 iron heads and found I did not have enough clearance on the intake valve. The relief needed to be widened as well as made deeper. The exhaust had good clearance in my case. Just something to watch out for when running stock pistons.
I have the big brother to this cam, the xe282hr going into a 347 I'm building atm, also because of Richard Holdener. Seems to work well! How you like it and get it dialed in!
Dang, that’s a big ol’ cam! I’m still liking the 274 and it’s completely happy as a daily. Still don’t know it’s all out performance. I have a stock style Duraspark dizzy and really need to limit the mechanical advance, I’ve only been putting it off for four years 😬
@@fomobros2207 I really like it alot so far I've just ran on street. After Track opens and I get few passes then I'm gonna change to my newer Xe274hr motor and see which is faster.
I’ve replied to similar questions about the same way, apologies if my answer sounds generic now: I had a few extra bucks and I wanted to do something with the car and Richard Holdener speaks highly of the Xe274hr so I went with it…..however watching this video from David Vizard czcams.com/video/y_ZUdTd2IcY/video.html makes me think I shoulda coulda woulda went with a different cam….it’s a long winded way to say IDK 🤷♂️ I also had recently moved from sea level to high altitude sooooo that’s another big variable
This is a great video thank you for sharing I bought this same cam for my 95 GT I was wondering what size pushrods are you using thank you in advance!! 🐎💪
I’ve had three different cams in this engine and I haven’t had to change pushrod sizes yet. I have a 351 Windsor with 7.7” pushrods. Whatever pushrods you have “should” be fine
What ignition timing you running I got the same cam and off idle mine falls on it’s face then gos. Have a msd distributor and ignition sitting at 14 deg timing.
It was 36 total and I think 16 initial. I’m just shooting from the hip, but I’ve had a similar issue bc my idle mixture screws were too far in/lean. It might help to back them out and see if it does any good
302" cars run stronger with a 110* LSA. The wide LSA is to reduce the computer going nuts. I ALWAYS run a 15# oil pressure switch hooked to a red light and an 100 DB piezeo buzzer. JMO.😎
I appreciate that. I have World Windsor Jr.’s they have 1.94 and 1.60 valves. With hypereutectic Keith Black pistons. If you need the part number on the piston’s I may be able to get that for you.
@@fomobros2207 That won't be necessary!! Thanks for replying so quickly! I am rebuilding a Windsor and was curious! I'm running stock short block, prob. gonna have some clearance issues. SMH LOL. I have a long way to go. My heads have 2.02 intake valves. I'll be running same cam, as you are. I appreciate your input!!
The biggest question is how much better does it perform over the f cam? Is the drivability better or worse? Does it sound like a bigger or smaller cam than the f cam?
I don’t have time slips or dyno sheets to back anything up. The drivability was fine with the F303 and is also fine with the 274HR. It might sound a little smaller than the F303. The 274 does make a bit more vacuum at idle. I wish I could give some better data, but this ol’ Fox is my daily so if it’s not running then I’m walking. I am building up another 351W with the hopes to have a mild and a wild engine that can be swapped out in a weekend and maybe I can get some data for this cam aside from higher vacuum readings🤣😆
Did the cam seem to help it power wise any , I got the xe284 for my 347 build and have heard good things about the xe line of cams from comp , I haven't got my motor dropped in yet cause I got to get my heads milled that I just finished porting then I will be able to cruise on with the build I hope, its about to eat my wallet alive 😁
That’s the problem. Once you price everything out and set a reasonable budget for the build that’s all you get...the build. The budget gets blown before your half way done lol. I know that 347 is going to be a mean machine and equally as important I know as much as you that the engine is an investment. Man, to be honest I’ve mostly been cruising in this old car since I put it back together...for the second time. I’m really hoping to get the timing we’re it needs to be, since I’m running an Oreilly’s Duraspark distributor I have too much total timing so I’ve been looking through the JY to find a dizzy with less mechanical advance to cannibalize and at least have the timing dialed in
@@fomobros2207 you're right my budget got blown up about 25% into the build and it's kinda my fault because I started wanting bigger and better stuff because I knew that I would want to go faster than my previous plans would allow and I knew that I would want to be happy with it when I got finished with it so I started doing more machine work and buying more stuff to squeeze every ounce of hp I can out of it so I got greedy and it has come back to bite me in the wallet big time 🤑 but maybe now when I get finished I can focus on the other stuff instead of swapping parts out on the engine trying to squeeze out all of the power I can out of it because I already have so I can move on to the suspension and interior work and paint so hopefully it will perform the way I am planning it to anyway but it shouldn't take much to move a pinto down the road fast as light as they are but yeah when you get your timing right let me know how she feels, I bet it is going to be fun for sure 😁👍🏻
Two things... both of those cams will make you EXTREMELY happy! The 84 is racy for sure. The 74 is a beast and a perfect balance for all around performance.
You made the right choice this is a great performing cam!! But do you remember what size pushrods you used for your application I'm literally building the exact same motor that you have Any info would be very helpful thanks.👍
I really think I bought trick flow hardened pushrods that are 7.70”. I bought them back in 2012 so my memory is fuzzy. When I put the engine together it had an E cam. I’ve changed cams three times without changing anything else in the valvetrain. I have Howard’s retro fit hydraulic roller lifters as well.
Kinda new at this and got a 1995 f150 351w 5.8 4x4 stock. I want to use this cam XE274H cam. Any recommendations on what to use. Like which rockers and lifters and valve springs kinda confusing to me. Or me just being doubtful. Ty in advance
That sounds like a cool rig! I’ve had three cams in this car and have reused the same lifters, pushrods, and rockers each time. Since you car is a 1995 it’s a roller cam (unless someone engine swapped it) so you “should” be able to reuse your lifters, rockers, and pushrods if you want. Over the years I’ve had the E cam, B cam, F cam and currently the Xe274hr. Personally the toughest/best sounding cam to me was the E cam🤷♂️.
Hey me again ordered my springs, caps, and clips. I noticed in your comments, it's amazing how deep your pockets can go trying to get a good set of appordable roller rockers. What has worked out good for you? What could you recommend? I mentioned before this is all new to me.
John C I would like to give you good advice, better advice than I can, if that makes sense. So I have Crane Roller Rocker arms and I’ve been told they mixed reviews. They’ve been good to me so far. If you can hang tight I’ll have my brother Richard chat with you, his handle is Sikulz9550. He’s pretty good at going fast without spending unnecessary money. He’s been unlucky a couple times which just makes him a more discerning budget builder lolol
Hey man, as far as affordable roller rockers go, I would try to find some used ones like crane comp or scorpion. New rockers are soo expensive. I don’t have any personal experience with ProForm but I’ve read multiple bad reviews on them, from Ford and Chevy guys apparently the trunnions break, I don’t know if they’re bad or if they were misused i.e. too much spring pressure, coil bind, or too much RPM.....🤷♂️ good luck on your build John.
It's been some time since I spoke to you last curious how is the new cam working ou t for you. Got my heads all put together still on the fence about that new cam are you getting better results out of the new cam or the f303
I’m still looking for a centrifugal advance with smaller slots. Right now I have too much advance so I’m afraid to really wind it up. For a daily it’s still happy and it sounds better at idle than the F (in my opinion). As far as full out performance I can’t give an honest answer though. In a perfect world I would have dialed in the car with the F cam before putting the Xe274hr in, but I had money in my pocket and a long weekend so I just sent it lol
Appreciate all the information. For me it's hard to find time but when I do I enjoy tinkering with this 302. I'm not a young man about 30 years ago I used to own a 65 ranchero with a 289 in it unfortunately I wrapped that around a telephone pole. Had a 72 Ford ranchero with a big block in it had a lot of fun with it I'm 59. And recently got back into tinkering with these motors it has been fun. Talk to you later
@@fomobros2207 I just weld up the slot to limit the advance. There are a half dozen factory slots, so have always gone the easy route. Just set it by marking the balancer at 36 degrees, unplug the vacuum and rev it to set. I then put an air bleed nipple with a vacuum plug, on the vacuum line and melt a hole to get the right amount of advance. This introduces an air bleed into the system.
@@rondye9398 I can weld, just not confident in my ability to weld the advance slot lol. My bro and I came up with a cool idea though, we used heat shrink to take up the slot until we got it the right thickness. That air bleed stuff is a little over my head lol. I’ll have to look into it, in the meantime I just plug the vacuum advance and only rely on the centrifugal
This one is a 351W with Keith Black pistons. They have pretty large valve reliefs so I just sent it without pulling the heads and checking piston to valve clearance
It’s just bc you have to remove the lifters to pull the cam. However, there is a kit that is basically a magnet shaped sort of like a push rod with a wing nut. It allows you to lift the lifters magnetically so you don’t have to pull the intake to swap cams
Overall yes. The vacuum gauge shows that I have a bit less Hg than I did with the F cam, but the drivability is unaffected. I've also been playing with the carb the past few days, initially I went too lean and I've been fattening it up a little each day, so the idle quality could get even better, but I think it will probably stay the same as it is now. A long winded answer to basically say 'Yeah it's fine' lol
I do half a turn past zero. Comp cams has the amount of preload in thousands of an inch, but I can’t remember off the top of my head. If it’s important I can find the instruction sheet and give you a real answer.
I hope you're running a composite gear. that factory steel gear is eating the hell out of your austempered cam. been there done that. comp cams tech sucks.
It’s an MSD steel gear, not sure if that makes it better than factory. But it’s funny you mention that bc my bro and I were just looking at my dizzy with the MSD gear vs another Frankenstein dizzy I put together with a stock steel gear. The wear pattern was looking worse on the stock steel gear after two weeks compared to the MSD gear after 4 years of use. So we put the dizzy with the MSD gear back in. Definitely something I’ll keep an eye on, thanks for the heads up 👍
Does it seem different than the F cam? I have an XE274HR in a 302 and it ran good. Too bad it is in a running car or I would put it in my own 351w vert. I have brought my 85 351w vert to the track a couple times and it only runs 101 mph. I figure the stock GT40 iron heads are holding it back. Mags say they flow about 190 cfm on the intake side. I have a pair of BluePrint pedestal mount 190 cc 2.02 1.60 60 cc heads that came on a crate engine and I have decided to put them on the 351w. Just finished using a dremel and sanding rolls to clean up the bowls a little and get rid of the casting flash in the ports. Hopefully start putting them back on today. Here are BluePrint's spec on the heads. Probably similar to the heads you have. Intake CFM Port Flow Average @ 28" .100" - 73 .200" - 120 .300" - 168 .400" - 203 .500" - 238 .600" - 240 Exhaust CFM Port Flow Average @ 28" .100" - 58 .200" - 104 .300" - 128 .400" - 146 .500" - 159 .600" - 166 I was going to leave the E303 cam in the car, but I have some other cams I could run. I like the bottom end I have now so I don't know if I will change it out. I have a XE266HR, the BluePrint cam which seems to be a copy of the XE266HR and a Lunati Voodoo on the shelf. Your video has me thinking now is the time to change the cam too. Here are the specs on the Voodoo: Hydraulic Roller Cam. High performance street/bracket cam. Needs 10:1 compression minimum, increased induction and exhaust. Needs 3.55+ gearing. Requires computer mods. Very strong above 3500 RPM.; Advertised Duration (Int/Exh): 282/290; Duration @ .050 (Int/Exh): 231/239; Gross Valve Lift (Int/Exh): .571/.587; LSA/ICL: 110/106; Valve Lash (Int/Exh): Hyd/Hyd; RPM Range: 2600-6600; Might be a bit big and I will lose the bottom end torque that makes this car fun to putt around in. I could run the XE266HR or BluePrint cam and not give up any bottom end and possibly gain over the E303. Or I could just leave the E303 in. Too many choices:)
So I basically just bought the cam bc I did have some spare cash and I just wanted to turn a wrench. There was only one tiny shred of logic behind the cam choice for me, aside from the kind things Richard H said about the cam. The tiny shred of logic is that my Windsor Heads are just a notch above GT40’s. Since you’ve done some work on your GT 40’s I am betting they flow super good now. So why do the Jr’s not flow to good? Well my brother thinks that the valves are too shrouded and if somebody took a dremel and took the edge off unshrouding the valves the heads would flow much better. I’ve never done port work and would rather practice on E7’s instead of the Jr’s. So the idea is with a larger lift cam the valves might make it far enough past the shrouded area to compensate for my lack of willingness to work the heads. I know it’s kinda silly, but I’m send it. Idk about your cam conundrum, that’s too many choices for me lol. I would be interested in the VooDoo cam that thing sounds insane!!! Or maybe you could put it in the 408 you didn’t know you were going to build jk. Thanks man!!
@@fomobros2207 I actually am taking the iron GT40s off and putting on the aluminum BluePrint heads that I used the dremel sanding rolls on to blend the bowls and clean up the casting flash. Hopefully it picks up a bunch. I am leaning toward leaving the E303 cam in and running some used 1.7 Cobra roller rockers on it. I probably will put the Voodoo cam in the 408. Next year the 408 (410 actually since it is 0.040 overbored) is going to be the engine for my strip / street car which is a 90 LX hatch that currently has a 302 in it with the XE274HR cam. That car has subframe connectors, manual brakes and manual steering. I would rather make the hatch the fast car and the vert the daily.
@@sbf_fox2434 So I guess I am part psychic, bc I didn't know you also had a 408/410 in the works. Either that or I just have a bad memory lol. Sounds like a solid plan!
@@fomobros2207 I bought a BluePrint 410 off the clearance rack at Summit a couple seasons ago. The head has 2016 stamped in it. Its more of a street engine with hypereutectic pistons, the XE266HR knockoff cam and the pedestal mount 190 cc intake heads. My plan is to upgrade the cam and heads to make it more of a strip / street engine. Last year I bought some used AFR205 heads for it. I am thinking either my TFS stage iii cam or the voodoo. Plan is to put it in my carbureted 90 LX. Last two years I have been concentrating on the 85 GT vert street car. I swapped in the roller 351w last year. It was the first engine I assembled myself. I filed the rings to set the gap, started to polish the crank with shoelaces and checked the bearing clearances with plastigage. A machine shop cleaned the block and checked it for cracks, bored and honed the block 0.020 oversized, installed freeze plugs and cam bearings, pressed the pistons on the rods, finished polishing the crank (looks like I could have finished it myself) and resurfaced the heads. I put on a set of iron GT40s with upgraded springs I had previously had an old timer work on. He had lapped the valves on them. Did not do too much this year. My ProComp distributor in the 351w vert had its module fail and I spent some time trouble shooting the ignition. Turns out I was not getting full voltage to the TFI coil or the power lead to the distributor. I tried an MSD digital 6al I got from the Summit clearance rack and I eventually figured out it was bad. I sent it back to MSD and they fixed it for about $60. Current ignition system is a pricey MSD pro billet distributor, digital 6AL and a premium TFI coil. I also did some work on the carb and am trying a 770 truck avenger now. Raced it a couple times and it does not mph too well. I broke the 7.5 differential a few weeks ago so I swapped a 3.55 8.8 into it. I also worked on the rear drum brakes with the axle swap. Hope to get the Blueprint heads on by Friday so I can race it. I was unhappy to find when I fill the ports with gas it leaks past the valves. I have been working on lapping the valves in. I don't want to spring for a valve job on these "new" heads. One intake valve of the 16 valves was not leaking. All others had some gas seepage. I lapped them all once and some of the intake valves sealed up, but I still have some small leakage out all the exhausts and 4 of the intakes. Now its round 2 with the lapping. Hope its worth it.
If the valves don't seal after lapping them a second time, I am going to spring for a valve job on my NEW cylinder heads. Kind of disappointed, but better to get it done now than to wonder why the engine doesn't make power. Hopefully I can get it done for under $200. Maybe the valves will seal after lapping another time, but I kind of doubt it.
Lol, I’ll never know. I think I checked one or maybe two lobes to make sure it was close to the correct lift. But if the LSA or duration was off I’d never know it🤣. But that goes for all the cams I’ve put in🤷♂️. I’ve had this cam in for over a year and I don’t plan on changing it👍
The heads are World Windsor Jr.’s if I could go back I would have gotten the Sr.’s though. And I make about as much sense as a penny, and that’s on a good day
@@fomobros2207 ok ok .. but do you race your car so that you can feel or see (time slip) what cam do better .. or its just for fun??

@@Diondo26 noice! Sounds like a mean machine!! I see exactly what you’re saying, short answer: I do it for fun (I don’t race ☹️) but this also gives me a quick chance to explain the channel.

$ 20 went off with my son driving and stereo blaring. He was stopped before the lifters started clacking.
I always pop out those little galley plugs, then drill and tap the holes for screw in plugs.
I remembered your video on that as soon as I found that plug. The next engine is definitely getting tapped plugs
might want to think about having 2 pumkins a 3.00/3.25 geared for cruising & 3.50/3.73/4.10 gear for at the track. the Comp Cam XE274HR & Valve Springs might help (but what about your Intake VAC?) if you need More Power, add a 75 to 150 shot of NOS.

I agree about the valve springs. The car is a five speed. I like the idea of a track mode and a hot rod mode. But I think I’ll eventually have two old fords one I can beat on and one to daily. I realized I don’t have the means for one car that can do it all. Thanks

Will do. Fair warning I sometimes work at a snails pace. I really need to get the mechanical advance dialed back on this dizzy (should have taken care of that years ago, like when I had the E cam or the F cam in). But I am feeling motivated to get this thing dialed and I'll let you know.
@@fomobros2207 I just picked up a 93 f150 with a 302. When I get ready to put that cam in what would you suggest on an upgrade for affordable springs? I have picked up an extra set of heads that have been ported and polished but the springs are stock. I'm replacing all the EFI with RPM air gap, 650 Holly. I'm new to this game and I appreciate your knowledge.
John C my apologies for the late reply, somehow I missed this comment til now. I like name brand parts and I’m not very biased either. Which heads are you putting in the car? Are they E7’s or something better?
If you look on Summit at the XE274HR cam it shows suggested parts which includes comp can valve springs that are around 80 dollars
I did a little more digging around on Summit and found someone else asked what springs to use. Comp Cams answered with this part number: 987-16. They are 91 bux for just the springs...and it looks like another 50 bux for retainers.
@@fomobros2207 thank you so much. Time that you took to do all that research I really appreciate it. How is your car doing after you put the cam in it were you able to tune it to get more power. Thank you again I'll keep you updated I do enjoy watching your brother on his project motor.
For guys wanting to run the XE274HR on a stock 302 bottom end, check your piston to valve clearance. I put the smaller XE266HR in a stock bottom end 90 HO motor with GT40 iron heads and found I did not have enough clearance on the intake valve. The relief needed to be widened as well as made deeper. The exhaust had good clearance in my case. Just something to watch out for when running stock pistons.
Could always degree the cam to get it to work, without needing to notch the pistons.
I have the big brother to this cam, the xe282hr going into a 347 I'm building atm, also because of Richard Holdener. Seems to work well! How you like it and get it dialed in!
Dang, that’s a big ol’ cam! I’m still liking the 274 and it’s completely happy as a daily. Still don’t know it’s all out performance. I have a stock style Duraspark dizzy and really need to limit the mechanical advance, I’ve only been putting it off for four years 😬
Awesome Video
Thanks man! I clicked on one of your vids and notice you had the XE282HR cam. How are you liking that one?
@@fomobros2207 I really like it alot so far I've just ran on street. After Track opens and I get few passes then I'm gonna change to my newer Xe274hr motor and see which is faster.
Does comp cam have more power than the f303 cause i want to swap my f303 for the xe274hr but hope it's worth it
I’ve replied to similar questions about the same way, apologies if my answer sounds generic now: I had a few extra bucks and I wanted to do something with the car and Richard Holdener speaks highly of the Xe274hr so I went with it…..however watching this video from David Vizard czcams.com/video/y_ZUdTd2IcY/video.html makes me think I shoulda coulda woulda went with a different cam….it’s a long winded way to say IDK 🤷♂️ I also had recently moved from sea level to high altitude sooooo that’s another big variable
This is a great video thank you for sharing I bought this same cam for my 95 GT I was wondering what size pushrods are you using thank you in advance!! 🐎💪
I’ve had three different cams in this engine and I haven’t had to change pushrod sizes yet. I have a 351 Windsor with 7.7” pushrods. Whatever pushrods you have “should” be fine
What ignition timing you running I got the same cam and off idle mine falls on it’s face then gos. Have a msd distributor and ignition sitting at 14 deg timing.
It was 36 total and I think 16 initial. I’m just shooting from the hip, but I’ve had a similar issue bc my idle mixture screws were too far in/lean. It might help to back them out and see if it does any good
302" cars run stronger with a 110* LSA.
The wide LSA is to reduce the computer going nuts.
I ALWAYS run a 15# oil pressure switch hooked to a red light and an 100 DB piezeo buzzer.
JMO.😎
I couldn't find what heads you're using/valve sizes and what pistons? Great video! looking forward to your next video!! Thank You!!
I appreciate that. I have World Windsor Jr.’s they have 1.94 and 1.60 valves. With hypereutectic Keith Black pistons. If you need the part number on the piston’s I may be able to get that for you.
@@fomobros2207 That won't be necessary!! Thanks for replying so quickly! I am rebuilding a Windsor and was curious! I'm running stock short block, prob. gonna have some clearance issues. SMH LOL. I have a long way to go. My heads have 2.02 intake valves. I'll be running same cam, as you are. I appreciate your input!!
What pistons are you using in that motor?
Silvolite’s
Part number: uem 1171hc
The biggest question is how much better does it perform over the f cam? Is the drivability better or worse? Does it sound like a bigger or smaller cam than the f cam?
I don’t have time slips or dyno sheets to back anything up. The drivability was fine with the F303 and is also fine with the 274HR. It might sound a little smaller than the F303. The 274 does make a bit more vacuum at idle. I wish I could give some better data, but this ol’ Fox is my daily so if it’s not running then I’m walking. I am building up another 351W with the hopes to have a mild and a wild engine that can be swapped out in a weekend and maybe I can get some data for this cam aside from higher vacuum readings🤣😆
Hey man is this the stock block?
Yes, it’s an ‘86 Bronco block with a .030” over bore and a refurbished stock crank
Did the cam seem to help it power wise any , I got the xe284 for my 347 build and have heard good things about the xe line of cams from comp , I haven't got my motor dropped in yet cause I got to get my heads milled that I just finished porting then I will be able to cruise on with the build I hope, its about to eat my wallet alive 😁
That’s the problem. Once you price everything out and set a reasonable budget for the build that’s all you get...the build. The budget gets blown before your half way done lol. I know that 347 is going to be a mean machine and equally as important I know as much as you that the engine is an investment. Man, to be honest I’ve mostly been cruising in this old car since I put it back together...for the second time. I’m really hoping to get the timing we’re it needs to be, since I’m running an Oreilly’s Duraspark distributor I have too much total timing so I’ve been looking through the JY to find a dizzy with less mechanical advance to cannibalize and at least have the timing dialed in
@@fomobros2207 you're right my budget got blown up about 25% into the build and it's kinda my fault because I started wanting bigger and better stuff because I knew that I would want to go faster than my previous plans would allow and I knew that I would want to be happy with it when I got finished with it so I started doing more machine work and buying more stuff to squeeze every ounce of hp I can out of it so I got greedy and it has come back to bite me in the wallet big time 🤑 but maybe now when I get finished I can focus on the other stuff instead of swapping parts out on the engine trying to squeeze out all of the power I can out of it because I already have so I can move on to the suspension and interior work and paint so hopefully it will perform the way I am planning it to anyway but it shouldn't take much to move a pinto down the road fast as light as they are but yeah when you get your timing right let me know how she feels, I bet it is going to be fun for sure 😁👍🏻
Two things... both of those cams will make you EXTREMELY happy! The 84 is racy for sure. The 74 is a beast and a perfect balance for all around performance.
You made the right choice this is a great performing cam!! But do you remember what size pushrods you used for your application I'm literally building the exact same motor that you have Any info would be very helpful thanks.👍
I really think I bought trick flow hardened pushrods that are 7.70”. I bought them back in 2012 so my memory is fuzzy. When I put the engine together it had an E cam. I’ve changed cams three times without changing anything else in the valvetrain. I have Howard’s retro fit hydraulic roller lifters as well.
@@fomobros2207 I appreciate the info sure sounds good to me thanks!!🇺🇸💪
Kinda new at this and got a 1995 f150 351w 5.8 4x4 stock. I want to use this cam XE274H cam. Any recommendations on what to use. Like which rockers and lifters and valve springs kinda confusing to me. Or me just being doubtful. Ty in advance
That sounds like a cool rig!
I’ve had three cams in this car and have reused the same lifters, pushrods, and rockers each time. Since you car is a 1995 it’s a roller cam (unless someone engine swapped it) so you “should” be able to reuse your lifters, rockers, and pushrods if you want.
Over the years I’ve had the E cam, B cam, F cam and currently the Xe274hr. Personally the toughest/best sounding cam to me was the E cam🤷♂️.
@@fomobros2207 well thank you for the info much appreciated well hopefully I can put it back together lol but let's hope for the best.. I know I am
Supercool man 😂🤙🤙
Hey me again ordered my springs, caps, and clips. I noticed in your comments, it's amazing how deep your pockets can go trying to get a good set of appordable roller rockers. What has worked out good for you? What could you recommend? I mentioned before this is all new to me.
John C I would like to give you good advice, better advice than I can, if that makes sense.
So I have Crane Roller Rocker arms and I’ve been told they mixed reviews. They’ve been good to me so far. If you can hang tight I’ll have my brother Richard chat with you, his handle is Sikulz9550. He’s pretty good at going fast without spending unnecessary money. He’s been unlucky a couple times which just makes him a more discerning budget builder lolol
Hey man, as far as affordable roller rockers go, I would try to find some used ones like crane comp or scorpion. New rockers are soo expensive. I don’t have any personal experience with ProForm but I’ve read multiple bad reviews on them, from Ford and Chevy guys apparently the trunnions break, I don’t know if they’re bad or if they were misused i.e. too much spring pressure, coil bind, or too much RPM.....🤷♂️ good luck on your build John.
@@Sikulz thank you so much! Really appreciate your advice. I'll probably lean on the scorpions.
It's been some time since I spoke to you last curious how is the new cam working ou t for you. Got my heads all put together still on the fence about that new cam are you getting better results out of the new cam or the f303
I’m still looking for a centrifugal advance with smaller slots. Right now I have too much advance so I’m afraid to really wind it up. For a daily it’s still happy and it sounds better at idle than the F (in my opinion). As far as full out performance I can’t give an honest answer though. In a perfect world I would have dialed in the car with the F cam before putting the Xe274hr in, but I had money in my pocket and a long weekend so I just sent it lol
Appreciate all the information. For me it's hard to find time but when I do I enjoy tinkering with this 302. I'm not a young man about 30 years ago I used to own a 65 ranchero with a 289 in it unfortunately I wrapped that around a telephone pole. Had a 72 Ford ranchero with a big block in it had a lot of fun with it I'm 59. And recently got back into tinkering with these motors it has been fun. Talk to you later
@@fomobros2207 I just weld up the slot to limit the advance. There are a half dozen factory slots, so have always gone the easy route. Just set it by marking the balancer at 36 degrees, unplug the vacuum and rev it to set. I then put an air bleed nipple with a vacuum plug, on the vacuum line and melt a hole to get the right amount of advance. This introduces an air bleed into the system.
@@rondye9398 I can weld, just not confident in my ability to weld the advance slot lol. My bro and I came up with a cool idea though, we used heat shrink to take up the slot until we got it the right thickness. That air bleed stuff is a little over my head lol. I’ll have to look into it, in the meantime I just plug the vacuum advance and only rely on the centrifugal
Can you use the XE274HR in Y-Block´s?
What year 302 motor ? I have a 85 mustang 302 and I was told because of flat top pistons that I would be limited on cam and heads
This one is a 351W with Keith Black pistons. They have pretty large valve reliefs so I just sent it without pulling the heads and checking piston to valve clearance
Newbie here! Wow why do you have to take out the intake to put a cam in?
It’s just bc you have to remove the lifters to pull the cam. However, there is a kit that is basically a magnet shaped sort of like a push rod with a wing nut. It allows you to lift the lifters magnetically so you don’t have to pull the intake to swap cams
Is the idle quality about the same with both cams?
Overall yes. The vacuum gauge shows that I have a bit less Hg than I did with the F cam, but the drivability is unaffected. I've also been playing with the carb the past few days, initially I went too lean and I've been fattening it up a little each day, so the idle quality could get even better, but I think it will probably stay the same as it is now. A long winded answer to basically say 'Yeah it's fine' lol
What did you set your preload at. Thanks
I do half a turn past zero. Comp cams has the amount of preload in thousands of an inch, but I can’t remember off the top of my head. If it’s important I can find the instruction sheet and give you a real answer.
@@fomobros2207 No that's fine. I'm running the x303 and was just curious what you set preload. Thanks for the reply.
I hope you're running a composite gear. that factory steel gear is eating the hell out of your austempered cam. been there done that. comp cams tech sucks.
It’s an MSD steel gear, not sure if that makes it better than factory. But it’s funny you mention that bc my bro and I were just looking at my dizzy with the MSD gear vs another Frankenstein dizzy I put together with a stock steel gear. The wear pattern was looking worse on the stock steel gear after two weeks compared to the MSD gear after 4 years of use. So we put the dizzy with the MSD gear back in. Definitely something I’ll keep an eye on, thanks for the heads up 👍
@@fomobros2207 pull the dizzy out again and look at the teeth on the cam itself. if its shiny and looks like a razor, you have problems.
Why would you use a wide LSA cam with a carb?
Richard Holdener spoke very highly of this cam, I had a few extra bucks, and I just sent it
I suggest you check David Vizard.
RH likes the cam from his computer experience and it works ok with a carb... But an 110* LSA makes more power.
Turn the idle up
Does it seem different than the F cam? I have an XE274HR in a 302 and it ran good. Too bad it is in a running car or I would put it in my own 351w vert.
I have brought my 85 351w vert to the track a couple times and it only runs 101 mph. I figure the stock GT40 iron heads are holding it back. Mags say they flow about 190 cfm on the intake side. I have a pair of BluePrint pedestal mount 190 cc 2.02 1.60 60 cc heads that came on a crate engine and I have decided to put them on the 351w. Just finished using a dremel and sanding rolls to clean up the bowls a little and get rid of the casting flash in the ports. Hopefully start putting them back on today.
Here are BluePrint's spec on the heads. Probably similar to the heads you have.
Intake
CFM Port Flow Average @ 28"
.100" - 73
.200" - 120
.300" - 168
.400" - 203
.500" - 238
.600" - 240
Exhaust
CFM Port Flow Average @ 28"
.100" - 58
.200" - 104
.300" - 128
.400" - 146
.500" - 159
.600" - 166
I was going to leave the E303 cam in the car, but I have some other cams I could run. I like the bottom end I have now so I don't know if I will change it out. I have a XE266HR, the BluePrint cam which seems to be a copy of the XE266HR and a Lunati Voodoo on the shelf. Your video has me thinking now is the time to change the cam too.
Here are the specs on the Voodoo: Hydraulic Roller Cam. High performance street/bracket cam. Needs 10:1 compression minimum, increased induction and exhaust. Needs 3.55+ gearing. Requires computer mods. Very strong above 3500 RPM.; Advertised Duration (Int/Exh): 282/290; Duration @ .050 (Int/Exh): 231/239; Gross Valve Lift (Int/Exh): .571/.587; LSA/ICL: 110/106; Valve Lash (Int/Exh): Hyd/Hyd; RPM Range: 2600-6600;
Might be a bit big and I will lose the bottom end torque that makes this car fun to putt around in. I could run the XE266HR or BluePrint cam and not give up any bottom end and possibly gain over the E303. Or I could just leave the E303 in. Too many choices:)
So I basically just bought the cam bc I did have some spare cash and I just wanted to turn a wrench. There was only one tiny shred of logic behind the cam choice for me, aside from the kind things Richard H said about the cam. The tiny shred of logic is that my Windsor Heads are just a notch above GT40’s. Since you’ve done some work on your GT 40’s I am betting they flow super good now. So why do the Jr’s not flow to good? Well my brother thinks that the valves are too shrouded and if somebody took a dremel and took the edge off unshrouding the valves the heads would flow much better. I’ve never done port work and would rather practice on E7’s instead of the Jr’s. So the idea is with a larger lift cam the valves might make it far enough past the shrouded area to compensate for my lack of willingness to work the heads. I know it’s kinda silly, but I’m send it.
Idk about your cam conundrum, that’s too many choices for me lol. I would be interested in the VooDoo cam that thing sounds insane!!! Or maybe you could put it in the 408 you didn’t know you were going to build jk. Thanks man!!
@@fomobros2207 I actually am taking the iron GT40s off and putting on the aluminum BluePrint heads that I used the dremel sanding rolls on to blend the bowls and clean up the casting flash. Hopefully it picks up a bunch. I am leaning toward leaving the E303 cam in and running some used 1.7 Cobra roller rockers on it.
I probably will put the Voodoo cam in the 408. Next year the 408 (410 actually since it is 0.040 overbored) is going to be the engine for my strip / street car which is a 90 LX hatch that currently has a 302 in it with the XE274HR cam. That car has subframe connectors, manual brakes and manual steering. I would rather make the hatch the fast car and the vert the daily.
@@sbf_fox2434 So I guess I am part psychic, bc I didn't know you also had a 408/410 in the works. Either that or I just have a bad memory lol. Sounds like a solid plan!
@@fomobros2207 I bought a BluePrint 410 off the clearance rack at Summit a couple seasons ago. The head has 2016 stamped in it. Its more of a street engine with hypereutectic pistons, the XE266HR knockoff cam and the pedestal mount 190 cc intake heads. My plan is to upgrade the cam and heads to make it more of a strip / street engine. Last year I bought some used AFR205 heads for it. I am thinking either my TFS stage iii cam or the voodoo. Plan is to put it in my carbureted 90 LX.
Last two years I have been concentrating on the 85 GT vert street car. I swapped in the roller 351w last year. It was the first engine I assembled myself. I filed the rings to set the gap, started to polish the crank with shoelaces and checked the bearing clearances with plastigage. A machine shop cleaned the block and checked it for cracks, bored and honed the block 0.020 oversized, installed freeze plugs and cam bearings, pressed the pistons on the rods, finished polishing the crank (looks like I could have finished it myself) and resurfaced the heads. I put on a set of iron GT40s with upgraded springs I had previously had an old timer work on. He had lapped the valves on them.
Did not do too much this year. My ProComp distributor in the 351w vert had its module fail and I spent some time trouble shooting the ignition. Turns out I was not getting full voltage to the TFI coil or the power lead to the distributor. I tried an MSD digital 6al I got from the Summit clearance rack and I eventually figured out it was bad. I sent it back to MSD and they fixed it for about $60. Current ignition system is a pricey MSD pro billet distributor, digital 6AL and a premium TFI coil.
I also did some work on the carb and am trying a 770 truck avenger now. Raced it a couple times and it does not mph too well. I broke the 7.5 differential a few weeks ago so I swapped a 3.55 8.8 into it. I also worked on the rear drum brakes with the axle swap. Hope to get the Blueprint heads on by Friday so I can race it. I was unhappy to find when I fill the ports with gas it leaks past the valves. I have been working on lapping the valves in. I don't want to spring for a valve job on these "new" heads. One intake valve of the 16 valves was not leaking. All others had some gas seepage. I lapped them all once and some of the intake valves sealed up, but I still have some small leakage out all the exhausts and 4 of the intakes. Now its round 2 with the lapping. Hope its worth it.
If the valves don't seal after lapping them a second time, I am going to spring for a valve job on my NEW cylinder heads. Kind of disappointed, but better to get it done now than to wonder why the engine doesn't make power. Hopefully I can get it done for under $200. Maybe the valves will seal after lapping another time, but I kind of doubt it.
Was the cam a bad grind?
Lol, I’ll never know. I think I checked one or maybe two lobes to make sure it was close to the correct lift. But if the LSA or duration was off I’d never know it🤣. But that goes for all the cams I’ve put in🤷♂️. I’ve had this cam in for over a year and I don’t plan on changing it👍
u do a lot of cam stuff ... but still running the Stock heads ?? doesnt make much sense..
The heads are World Windsor Jr.’s if I could go back I would have gotten the Sr.’s though. And I make about as much sense as a penny, and that’s on a good day
@@fomobros2207 ok ok .. but do you race your car so that you can feel or see (time slip) what cam do better .. or its just for fun?? I run the F cam in my stroker and it works very well ..just changed the heads from ported Floteks to Promaxx with the bigger valves ..dont know yet if it was worth the Money ..need some longer Pushrods ...next week I ll see...
@@Diondo26 noice! Sounds like a mean machine!!
I see exactly what you’re saying, short answer: I do it for fun (I don’t race ☹️) but this also gives me a quick chance to explain the channel. I’m Ray and I made this video. The oldest Brother Richard also posts on this channel he is the real deal, he’s been wrenching and racing for over 20 years and is pretty sharp.
