I enjoyed your video on porting the 460 heads I have some 69 heads i ported it really helped the engine to come alive and I had a 620 lift cam and a portosonic intake with a 750 holley on it in a 2500 lb car run 6.37 in the 1/8 mile std bore
Thank You for your kind words! Porting the 429/460 head makes a world of difference in them. I used to have a Portosonic intake. I should have kept it. Good intake for a hot street strip car.
Years ago I build a couple of sets of heads following guidelines such as you lay down here. I added a couple of things on the exhaust side, however, that I think really helped my heads. I filled the 'dead area' at the bottom of the exhausts with Devcon F to further maintain flow. Also 3-angle valve job (I and E). I was towing a 22 ft Great Divide camper with my '76 Ford van and could get 11 mpg up in Wyoming @ 6200 ft elevation traveling 65 to 70 mph fully loaded. If I wasn't towing, I could have all 6 of us plus all tent camping equipment and regularly achieved 18-19 mpg. I "tricked" my C6 with a shift kit and had a matched converter. I used TRW forged pistons with a 10.5/1 piston ratio. I carefully cut a flame channel on the piston top and my final compression ration was 10.3/1. Also advanced the cam 8 degrees and recurved the distributor to meet my needs. Also used water/alcohol injection for the hard pulls. Ran 16 degrees initial timing with a total of 34 degrees all in by 3000 rpm. I put a Comp Cam RV cam (don't recall lift and duration) and I had power everywhere. I regularly passed drivers on the interstate that I needed to with ease. Unloaded the van would spin the tires for nearly a block then snap-shift into second and spin again. Man, I miss that rig! It is unbelievable how these mods + others can help the 460. Even the 454 Chevy guys were amazed.
I don't doubt that filling the floor helped them. That was a common practice on the Cleveland heads and if you look at the exhaust port of the 460 fuel injected heads you will notice that the floor is raised on them and those are the highest velocity heads ever put of a 460! I've always said the the 460 needs three things to wake them up. Raise the compression up, open the exhaust side up, and straight up cam timing at the very least to do away with the 8 degrees that the camshaft is retarded from the factory from 1972-1986. So what you're saying about yours makes perfect sense to me.
I did the same thing to my 460 heads I ported them but I took the bump completely out and then I put flat top pistons in bump the compression up to nine and a half to one and installed Cobra Jet valves in my stock 460 heads
I have ported them before and removed the bump completely. Newer flow bench tests are showing that bringing it up like a wing helps direct the flow and they flow slightly better. Either way works far better than doing nothing to them. If I was building a 460 for a street/strip car I would definitely install Cobra Jet sized valves because I would be turning more rpms with a street strip 429/460. Not that it would hurt to install them in a lower rpm truck 460 but I don’t think they are needed as much in a lower rpm application. I think porting the exhaust and a good valve job will get the most bang for the buck out of a lower rpm 460 but that’s my opinion. Now if I was turning over 4,000-4,500 rpms often then yes I would definitely add the Cobra Jet sized valves
I have always been a believer in cylinder head porting and deburring. I have a small drill press that I use for back cutting and swirl polishing valves.
I tried the drill press method but the files were way too soft. I was even using Nicholson files. I agree with you on porting and deburring. There are very few if any cylinder heads made that can not benefit from some porting and deburring.
@@BlackLabGarage Intake valves I use a flat file but exhaust valves that are much harder I use a die grinder with a stone. For swirl polishing I use a fine grit sanding roll while the valve is spinning in the drill press and manipulate the die grinder for that neat looking swirl effect.
@@paintnamer6403 That's what I tried was brand new Nicholson flat files and then I tried using a new whet rock and neither one would touch those valves! They are just stock replacement valves so they shouldn't be that hard!
Building one of these right now. Great vid and I'll be doing the same on the exhaust ports before they head to the machine shop for a valve job. Thanks for the info!!
Great down to earth, well explained video sir. Like me, you know your 460's. I have a 73 block with D3 heads in my 67 Mustang gt. Were ported on the "Exhaust side" and port to gasket match on the intake side. No cam change at this time until Trick Flow heads cam and lifters etc go on it. Will also increase static compression to around 10:5:1. But currently, paired to a built C-6 trans and 4:11 in the 9" , headers, Performer rpm intake, MSD mechanical advance, 6al box, 750 holley carb makes a nice street engine. Thanks for sharing. Looking forward to more good content. Cheers from Motown/Dearborn.
Ford 429's are one of the best engines ever built. Labs are the best dogs! I had never had labs before until I got these and now I can't imagine having any other kind of dog!
I am liking the bolt snap trick. Seen guys put set screws that were hardened. I put two steel rods into the length of the heads but those holes are unplugged , but gasses don't heat up the thermac ports. Thoughts of plugs falling out .
I have heard of people putting rods all the way thru the head but I haven't ever tried it. I never could figure out why people use hardened set screws in those holes. They are way too hard to cut!
Scribe a gasket line on bearing blu, and always smooth out the floor, finger each port bit by bit, don’t get one girl too excited if you know what I mean, gently get them all to open up like pretty flowers- make them all the same as god intended-upside down
I loved the breaking of the bolt in the head! What you say about the 460 in a bit like the Clevland 4V exhaust. They are a bad compromise for a series of engines that can haul ass!
@@MsKatjie Both the 351C and 460 exhaust ports suffer from a U shape port but the port for the 460 is trying to support 109 more cubic inches than the one for the 351C.
Its a mistake to put too much emphasis on the exhaust side of these heads. The intake side needs about an equal amount of work. There is a ton of flow and velocity to be found in the intake port when the short side is reworked properly.
But this is on a lower rpm truck motor. That's why I said if I was porting a set for a drag engine or hot street engine it would be different. For that I would move to the bigger valves and do more work on the intake side also, but for a lower rpm truck motor using a stock intake I think the emphasis should be more on the exhaust side.
If you increase the flow in the intake port by properly reshaping areas of the port, valve job, choke sizing etc you will increase the mean port velocity which will help greatly even in a low RPM truck engine. @@BlackLabGarage
Thank you for the video. I just drilled and tapped my d3 heads as you demonstrated. My question to you sir is what kind of bolt material do I use? I have the high temp thread lock, any issues with the studs ever backing out of the casting?
I use a regular bolt because a hardened bolt is too hard on the carbide burrs. I've not had any problems with them backing out not just because of the high temp thread locker but also because the bolt itself is bottomed out in the the head which would also make it hard to come loose.
@@BlackLabGarage I really appreciate the feedback and look forward to learning more from your experience with these 460 engines. Slowly but surely I will have it together.
Most all of the Ford pushrod V8’s suffered from small exhaust valves and small exhaust ports. The small block Windsor family probably being the worst! Why they did that I have no idea?
Their engineers were not stupid. Blow down pressure is immense and very little is gained by a large exhaust. Intakes operate at atmospheric pressure of around 13-14 psi. Cleaning them up does not hurt. As Bob Glidden says of chopping off the entire upper portion of the exhaust on the cylinder head on a 351 C Pro Stock engine and adding a plate "It's only worth 10 hp at 9500 RPM!
I was thinking about doing it to my 1997 f250. Ive done lots of other heads with great success so it should be fun. What size are my exhaust valves now and how much bigger do you go on these? I am getting 12 mpg now anyway and good power stock
Be careful with those heads. While they can use a little improving, the fuel injected heads are some of the best heads that Ford ever put on the 460 engine. Especially the F3TE head which is what you should have on your engine. Ford finally figured out that velocity works and used it on those heads! If you cut too much out of the ports you will loose the velocity of those ports. So be careful porting them. Your valves currently should be 2.10" diameter intake and 1.65" exhaust. Those valve sizes will support close to 400hp. The older E7TE 460 fuel injected head has 1.95" intake valve. It does need a larger intake valve installed. If it was me I would say with the current valve sizes and have a three angle valve job done and do some porting on the intake and exhaust but concentrate mostly on the bowl.
I haven't put these on a flow bench but the stock exhaust port usually flows about 135cfm. Staying with the stock exhaust valve size but porting like I did will get you to 175-185cfm. Going with the bigger CJ sized exhaust valve and porting the bowl to match it gets you around 200cfm or slightly more.
is the exhaust side less finicky than the intake side in regards to the quality of the port job? I was watching a video on a guy porting the intake side and he was saying you can make them worse if you take out too much bc it will cause the air to bounce around more.
Actually I'd say it's the opposite. You don't want a perfectly smooth finish on the intake side because that will allow the fuel droplets to fall out of suspension and puddle up where as a rough texture on the intake will help keep the fuel droplets in suspension in the air. You have suction from the piston going down in the cylinder to draw the fuel in but the exhaust valve opens right after the explosion at top dead center as the piston is going down in the cylinder so it doesn't have the suction advantage that the intake side does. As far as cutting too much of the port out on either side will cause you to lose velocity which is important. Faster you can get the air in and out of an engine the more efficient and more power it will make. A good example would be the Boss 302 engine. They were absolutely dead on bottom end because the ports and valves were too large and had no velocity down low. Only when you were up in the rpm's would the ports come alive and have some velocity to them.
I'm assuming it's a D1VE block which they used until 1979. If it has the standard dished pistons it was advertised as 8.0:1 but in reality its probably a little lower than that. It's probably somewhere between 7.5:1 and 8.0:1.
How well do 72 heads flow? Guy local to me has a pair with his motor for sale. What else would you do different for a car motor? This one's going in a 72 torino
If they are the D2VE 429/460 head stay far away from them. They are an open chamber design and spark knock very easily. That’s why they was replaced by the closed chamber D3 head a year later. If they are the D2OE Police Intercepter casting then they are fine to use as they are very similar to a 429 Cobra Jet head. If I was to fix a set of D3VE heads for a stree/ strip car I would have Cobra Jet sized valves installed and do the same porting work except open the intake port opening up to Cobra Jet sized ports and run a Cobra Jet intake on it. Now you don’t have to do that because Ford installed Cobra Jet intake manifolds on standard cylinder heads on marine engines and left the port mismatch as is and they ran fine but personally I would match them or at least get them close.
Danny, the 72 was the worst 460 their worst engine, heads etc One big block turd. 1973 was redesigned a a lot better but not near as good as the 68-71 block and heads. Or, get a 460 out of an EFI truck, is pretty good also. Remember, after 1971 the compressions dropped to around 8:5:1, 205 HP, down from 68-71's 365 HP. Best early 460 stock heads are the DOVE heads.
