About to get a 2004 mach 1 this week! Thanks for the knowledge
Thank you for watching. Congratulations on the Mach 1!
This is by far one of my favorite videos that's out right now related to the 4V 281 engines. Phenomenal video Mike, extremely informative. Keep up the great work man I highly enjoy your videos with your knowledge!
Thank you Blake! Feel free to re-post it. I've got some other cool ones coming! I think you will really like them.
I've never had a single issue with the 4 thread heads. Just have to torque your plugs to spec, and you're golden. People launching plugs out the heads are more than likely cross threading the plug into the soft aluminum, even with 9 threads thats a recipe for disaster.
I completely agree. 144 inch pounds and you are golden when installing new plugs. A lot of people either didn't use a torque wrench or they used one that is on foot pounds that wasn't accurate at the lower readings. Thank you very much for watching!
Very informative I love the 4 valve 4.6 it's a marvel of engineering. I raced a 5.7 hemi Challenger 8 speed from a 60 in my stock 98 Mark VIII and I kept reeling him in each time it shifted. The 4 valves never stop making power! Even at 6500 redline
I completely agree, they are great engines and with the great flowing heads they love to pull all the way to redline! Thank you for watching Datiel!
my 4v swapped GT falls off hard after 6500, revs up to 7500
@@32v4.6 epic 🔥 the 4 Valve modular loves to rev I love that about it most. My 98 Pulls hard to 6500 limited by the factory ecu. I'm gonna keep mine stock other than an xpipe exhaust setup 🔥
I own a mach 1 and always looked for these details thanks
You are very welcome Scott. Let me know if you need any help.
04 cobra owner here...very impressive u knw ur stuff!!!!!
Thank you!
Thanks, I have an ‘03 Mach 1 and this is the first time I’ve heard an in depth discussion on the difference between the two engines.
Thank you very much for watching!
Great info! And love the run through without chop editing every two seconds. You have your thoughts in order and you keep the flow. Thumbs up 👍!
Thank you very much!
This is exactly the video I was searching for thank you
Andrew, thank you very much for watching. I really appreciate it!
great video I just put 3500 miles on my forged 5.3L 04 mach1. Eagle rods and Diamond custom pistons, forged crank.. pistons are 1/10000th in the hole with a mild cam . American racing catted long tube headers with X pipe Automatic with 4.10 gears. Modular head shop ported the heads Car ran an 11.70. keeping it NA. Car has a total 48k miles on the body and trans. we went with the 5.0 big bore cast iron block. great cruiser.
Very nice build! I’d like to see some pictures.
@@MikesGarageRoute66 will do. I'll post up a link. also need find the pic of the dropped sleeve in the aluminum block.
@@pwrshots 👍🏻
Simple explanation the cobra engine is bulletproof the mach1 engine is made of glass. People can comment and say whatever they want i have an 03 2.9 whipple cobra making 870 wheel no problems the last 3 years.the mach1 your pushing it at 450 wheel. Even with the best tune the mach wont last long at 450 wheel unless its a garage queen.
The 03/04 Cobra engine was one of the best engines ever made. A lot of Mach 1 blower guys are grenading with stock internals. I built mine stronger then most Mach 1's and it should handle a lot more then my ported Eaton can throw at it. Thank you very much for watching!
Great video, have both a 04 Mach and a 04 Marauder. Have to have a Marauder when you don't want to feel the road and have some room to put the legs out.
Both very nice cars. I’ve always wanted a Marauder. Eaton swapped Marauder would be even more fun 😁. Thank you for watching Wildbill!
@@MikesGarageRoute66 just picked up a silver birtch 04 marauder with an eaton swap and air to water intercooler. The thing rips
@@kevinkrause1877 Very nice 👍🏻
Awesome video Mike. I see your trophy on your desk from the Vintage Mustang show at the race track.
Thank you Len, hopefully you and your family had a good Thanksgiving. Hopefully next year we can meet up at some more events. I have a lot of cool things planned for both Mustangs. Thank you again for watching!
This is great information! and will certainly make me look smart in the upcoming Cars and Coffee meet ups in the spring!! Blake is right one of the most informative
Thank you, Blake is a really cool guy!
@@MikesGarageRoute66 yes Blake is a great guy!! I checked and noticed That my Mach1 was built in July/28/2003 according to my certificate, I assume it has the 9 thread heads? if so that is awesome!! it only has 23000 miles on it..
Great video. Great knowledge, just one thing i noticed you had incorrect. 01 Cobra have wap blocks and 99s are hit or miss with some having teksid and some wap
Thank you!
I'm going to do a built and boosted Mark8 one day. Way to keep education the community Mike. Didn't know the story about the Focus causing the Terminator project. Love the video
A boosted Mark VIII would be a cool project. As always thank you for watching.
Same here! Owned 8 of them since 2010
@@markneal3540 Very nice! Thank you for watching!
Very informative now I know how to rebuild my 03 Marauder for more horsepower
Hit me up if you have any questions Carlos. Thanks for watching!
04 cobra owner here, there allot of the GT S550 guys I think really may not understand how special the 03/04 cobra is.....maybe they do, tell u what allot of people are sleep n on, the ecoboost mustang, i have one, and the look on the GT guys face after i kill them, its so funny, even the scatpak guys, so funny, the fastest ecoboost mustang ran a 9.4 bill putnam ecoboost mustang, there is a vid here on youtube, the ecoboost is fords grand national
I completely agree and I have a EcoBoom as my daily. Great car and decent power. I have a lot of plans for it 🍺
Knew most of this, but you're right, I did learn a few things. My 03 vert has 828 at the wheels, but it also has 04 Mach 9-thread heads on it. The weak point remains I have still stock pistons, but everything else in the whole drivetrain is beefed up, including the Magnum and Strange yokes. Next wad of cash I get will go towards the pistons.
It’s sounds like you have a very nice Cobra. Thank you for watching!
What is done to it? That's respectable power
Such knowledge ole wise one
This is very nice informative video! I just bought an aviator and have been learning a lot. Very special ride. Thanks Alot.

Awesome video! Very informative about the differences between the engine’s 👍
Thank you for watching! They were both great engines.
Got the Aussie Boss260 5.4 4v with the 04 cobra r heads etc etc really been watching a lot of this stuff to find common parts between our modulars you the U.S modulars as U.S prices are much lower.
Ours uses the Windsor block, forged/steel 8 bolt crank etc
Thanks for the info 👍
Thank you for watching!
The cobra R heads were only installed on the 2000 cobra R mustangs. The the heads you have are exactly those on our 03-05 4v engines, but yours have different valves and springs.
@@apocalypseperformancetwcam8386 Thank you Todd.
Mike, this is awesome info! I say your the 4.6 Guru😎 Btw I didn’t know the auto mach 1 had a different crank. Keep the videos coming🏁
Thank you very much Paul!
@@MikesGarageRoute66 Do you know why they changed the crank for the auto Mach?
@@PaulDaFox Yes, according to Scott Hoag they needed to go with the cast crank to meet the price target and make the auto Mach 1 viable.
@@MikesGarageRoute66 Thanks Mike!
Great content! Just a heads up......In Australia, Ford sold a 2002 Cobra. Almost identical to the 2001, but they revised the front bumper a bit....... thanks again for the vid!
I would really like to see pictures of one. I have heard of it, but never seen it. Thank you very much for watching!
They basically had like 100 left over 01 and sent them there to be converted for right hand drive and be sold as 02 cobras but they was just like our 01. The terminator was supposed to be an 02 but they didn't get it out in time because they were snapping rods and had to result to going aftermarket manly h beams in the cobra because of this and made the car come out little later mid year and was released mid 02 as an 03.

Finally a video on the topic where the presenter really knows what the hell he's talking about. I was unaware of the Zollner pistons in the Terminators but otherwise the content was all old hat for me. The thing is it's all accurate as hell old hat presented well and that's really refreshing to see.
Thank you very much. Your comment really means a lot to me. There is too much incorrect information out there.
John Coletti, the Terminator, was his fairwell . Ford in the early 2000's was really decent.

Awesome vid man. Very well put together! Also just subscribed 🍻
Thank you very much Scott!
Pretty sure DB heads can’t be used on either bank and I believe the coolant flow issue has been updated for cylinder 7&8 as well for DB heads. (Still recommend the heads mod) great info.
Using the head cooling mod is always good. Thank you for watching!
@@MikesGarageRoute66 10/10 agree! Enjoy the content. I’d run the head mod on DC heads (Allegedly they fixed coolant problem in that casting) I’d like to see a video of you comparing head flow between B/C/etc.
Great video Mike. You got me thinkin about pistons now. 2618 or 4032 ? 91octane is best I can get locally so I’m guessing around 10psi max for my 4v. Maybe I should just reuse my 6 bolt crank, get better rods and 9:1 4032 pistons and good enough. I don’t need to beat mustangs just eco boost explorers
9:1 would be pretty safe with 10psi. You could probably go closer 9.5:1 with a little less timing on 91. It will have some more torque, especially when not in boost and being an auto. As always thank you for watching!
Azure Blue Mach1all the way.Great video Mike you know your 4.6,s

Checking in brother !
Sup brother thanks for watching!
Sir, you are the Dr. Jordan Petersen of Engines.. Thank You.
**take it as a compliment...
**original owner of an Azure Blue '03 Mach 1 w/33k..
Thank you very much for watching. It sounds like you have a very nice Mach 1.
😄 Watching you guys explain the motors of these cars, even owning one myself, I have learned so much. Thank you so much for sharing. 😇I have learned things through personal experiences, but you never know what could happen... Nice to know even more. ☺Also 100k miles on a funny car like the cobra... Not too freakin bad... Compare it to the Rx8, also a funny car... A special car, but they have to be rebuilt every 2 years. I'd trade 100k miles over the modern rotary. I also know nothing about cars. Just sharing my own experience 🙃
Experience is what we all live by. I used to work on rotaries as well. I had 2 Gen 1 RX7's. Both had 12A engines. Back in the day we would bridge port the rotaries and put them in Datsuns and Corolas. That was always fun. Thank you for sharing and watching the video!
Good video Bud.
Glad you liked it. Thank you for watching!
Great information, thanks!
Thank you Tominator!
They actually did make a 2002 Cobra, but for whatever reason it was exclusively sold only in Australia... Had a different hood... They only made 100 of them, and wound up making them right hand drive once they got shipped over
Very very true! You are absolutely right
I don't know if its the same as the other cobras but the 96-98 cobras have a forged cranks.
Yes they do, I was not sure if it was the same crankshaft or different. They most likely are the same.
Every cobra from 1996 to 2004 is forged crank
Great video thumbs up thumbs

Great video Mike 👌
Thank you for watching!
Very good knowledge presented well! Thanks! I have a 96 Cobra with 30k miles. What components would you swap out to make some more power but mainly make the engine bulletproof? Also, who would you recommend to rebuild your engine or build more power?
First I want to thank you for watching. I really appreciate it. On your 96 Cobra there are a lot of things you can do. For more power I would recommend a small amount of boost. Pound for pound it is the best investment. Centrifugal is probably the cheapest and most reliable power to add. Then stay around 5 to 6 pounds of boost. The other option is a 2.1 Kenne Bell which is also a really good option (personally I like the Kenne Bell). The key is not to get greedy with boost and enjoy the Cobra for what it is, a Great Car!
@mikes garage I will buy the rods if priced fairly.
Thank you for watching! The rods have already been sold.
Great Post Mike…Very informative!!! I’m wanting to build an 03/04 Terminator engine using the "WAP" Block instead of the Cast Iron, I know you said in the video that those blocks will support around 1,300/RWHP!!! Will it continuously support that safely?
That's a good question. I would get a Teksid block if you are going big. Thanks for watching and let me know how the build turns out.
Great video
Thank you Gary!
Good info! I own a 04 Mach 1.
Thank you very much for watching!
i had an 01 cobra stock engine with a p1sc, and it blew up with a safe tune at 460 rwhp. the mach 1 is the same engine as the 01 cobra. 03-04 cobra is vastly superior engine.
@@motaz1975 I completely agree 👍🏻
Well done bud! Keep the 4V Mach stuff coming!
Thank you very much Nick! I have some content coming on the history of the 01 Bullitt and the 03/04 Mach 1. Thank you again for watching!
Kellog crank FTW!
Absolutely 👍🏻
Hello, I have a 118000 mile 03 cobra I chance the oil every 3 or 4 thousand miles,, From 2006 till 2010 it was a used on the freeway only 80 000 miles where from freeway only , the car runs strong, no leaking anywhere,, no oil consumption and absolutely never been abused,
It sounds like you have a very nice Cobra that has been well taken care of. Thank you very much for watching and leaving a comment.
Great video Mike! How about the intake manifold? Is there a difference between the 1999 to 2005 cobra, Aviator stock manifold, NA?
Hi Mark, there is a huge difference in the Intake. The 03/04 Cobra has no runner length which is actually hurts hp. The better manifold is the Mach 1/ Marauder, but it can be improved by having it turned into a short runner. Richard Holdener did a really good video on power adders for the Cobra and you can see the difference runner length makes. czcams.com/video/h4OHdC3nAFk/video.html
Great video Mike! Always super informative 🙏🏻
Thank you sir!
I had heard or read that there were actually 2 different pistons made for the 03 cobra. They changed from one to the other sometime during production. My cousin wants to put a short block from an aviator in his 5 speed Mach 1 as a replacement. Just a 6 bolt flywheel is all he would need I assume?
I heard that as well on the pistons but had a hard time finding information on that. The 6 bolt flywheel should mount right up. Another viewer mentioned when he went to replace the clutch on his Mach 1 he got a surprise when it was a 6 bolt. Somebody had swapped in a different motor at some point. Thanks for watching Justin!
Dang! Haha. Well I guess we know people have manual swapped an auto Mach 1 before too.
Things I were not aware of: The JE Pistons and being able to get on par with the coyote's but with an even stronger block. Also when you mentioned the 96-98 cams and how you can pick up power over the 03/04 cobra cams. Makes me wonder why more people do not go this route. Maybe because custom grind or comp just make that much more over the 96-98 cams? Also I've always wanted a rod from an 03/04 cobra and I know you wouldn't separate the set but I would be interested in the set of them as well. Let me know what you would want for them, I have a lot on my plate as far as what I'm already buying for the Cobra for mods but if its something I can swing I'd be interested in them.
96-98 cobra cams add very little in terms of peak power and reduce low end output. They aren't a good mod for terminators.
@@apocalypseperformancetwcam8386 Thank you for watching Todd. You build very nice custom cams!
Hi Travis, the point I really wanted to make at the end is that the Cobra is still relevant. Going with a domed piston that’s notched, thinner head gasket, zero decking the block, and milling the heads you can make a very high compression Cobra. Will it be quite as good as the Coyote, no, but it’s a damn good motor.
@@apocalypseperformancetwcam8386 Makes sense. Just wasn’t aware of that major differences between the two
@@MikesGarageRoute66 Definitely gave me some things to consider if the motor ever comes apart for whatever reason
Nice video Mike. Very educational love it.
Have a great evening sir 🇺🇸🏁🦍
Thank you very much for watching Silverback!
You know your shit buddy, entertaining video.
Thank you very much! It really means a lot!!
Awesome videos! Thanks for the content!
I have a question I have a mach1 with a aviator engine.. I ordered cams “233/237, .475" lift on a 113 LSA with a 1 degree advance” I haven’t installed them yet.. some shops have told me I’d need valve reliefs some have not.. would you happen to know if this size cam would require valve reliefs?
Great question David, I honestly do not know. Who would know is Todd Warren. You can find him on Facebook. Thank you for watching!
bolting coyote intake on my 4 valve right now and didnt take much to do so more for the look than performance
That's very interesting, can you tell me more about it? Thank you again for watching!
Excellent video!
Thank you very much and thanks for watching!
The one difference in the rods is also the design, one being an “I” beam design and the 03-04 being “H” beam
Very true, that and the material. I really dislike the OEM rods that they put on most mustangs. True it is cheaper, but mustang owners always want to push the limit on these engines! Thank you for watching!
Would using the camshafts from a 2005 Lincoln Aviator improve the HP/Torque in a 2002 Lincoln Continental?
They are using the same cams. If you find 96-98 Cobra cams, those have a better intake cam. I believe the duration is 204 instead of 186.
Would anyone know how much the crank on a automatic Mach can handle?
Great question. About 750 rwhp. The big killer for the cast crank is rpm’s. It’s best to keep it under 7k.
Great video very informative! Do you know if the Mach 1 and cobras have the same transmission because ik the cobras have a T56 and if not how much HP can the stock Mach 1’s handle?
Machs along with '01 cobra and '01 and up GT all got TR3650
The 03/04 Cobra has the T-56, the other Cobra's, the Mach 1's and GT's of that era all got the TR3650. The TR3650 is a pretty good transmission and can handle 500 to 550 horsepower, but the problem is the syncros wear out if you are banging the gears. Overall the TR3650 is not a bad transmission, especially with MGW shifter.
Very true Robin, you know your Mustangs!
@@MikesGarageRoute66 its only thanks to listening to people smarter than me, on channels like this! I have a Steeda Tri-ax on my TR3650. I dont plan to do anything besides adding 4:10's, so hopefully it lasts me. Has 100,000 miles on it now and all seems healthy.
4:10's should be pretty nice and depending on your tire size you should run about 2700 RPM's at 80MPH which isn't too bad. The 4R70W I have doesn't have as good of an overdrive gear so with a 3:55 I am at 2700RPM's. I just bought a Strange 9 inch with a 3:25 and that will bring me down to 2500 RPM's at 80MPH.
Thank you so much, Do you happen to know a good average price on a 04 Mach one stick, with low miles (27k)? I want a Mach one, just no idea on anything past 93. I’m a foxbody guy!
Thanks for watching. Depending on the area 16k to 19k
It’d be nice to build a aviator to show them tbss and jeep srt wassup
That would be very cool. Thank you very much for watching Orlando!
really great info!
Thank you very much Darrell!
Anyone who works on their vehicle understands how special hand assembly is
Very true!
Sry to Tell you but your wrong about the mach1 pistons ihave got two 04 mach 1 engines ones been disassembled an the other one has the heads off an they both have the same flattop pistons so I'm 100 percent fasure that their not dished pistons.
I thought the same thing until I put one on a belt sander. Then you can see the slight dish. Hit me up on Instagram and and I’ll show you the picture.
idon't think that it should take a belt sander to reveal a dished piston that totally looks flat as a pancake myman lol there flattops nodought unless sumone has swapped them for dished ones in your motor
What’s your thoughts on putting nitrous on 2003 Mach 1? That’s what I’m installing on my Mach 1.
I would not do over a 100 shot on a Mach 1 stock engine. Thank you for watching Dave!
I've seen a 2004 mach 1 for sale. It's one of those 40th anniversay ones in blue. It's a 4 valve but it's got cobra jet written on the side of the shaker. What does that refer to?
It’s just a decal that some people put on them. Kind of a throw back to the old Mach 1’s.
The teksid blocks weren't just 99 cobras it was also 96-98 cobras not sure about the mark 8 I think they might have had them too it was basically same as 96 cobra motor minus intake manifold as far as I know.
I believe you are right and the Mark VIII as well. They were very nice blocks. I was happily surprised that Sean Hyland was wrong on the WAP blocks. He had stated they were only good to north of 600hp. They have been successfully brought up to 1300 last time I checked. Thank you for watching!
@@MikesGarageRoute66 Wow, this is great news. I’m a little behind on the info but it makes me happy nonetheless! Cheers for that Mike!
Since the last time I commented on one of your videos I purchased another 2004 Mach 1. I still have my previous 2004 Azure Blue (bone stock), but this time the “new” 2004 I bought has just a hair over 66k and it’s been completely built as a dedicated NMRA car. Previous owner was retiring from the service and couldn’t take the car with him so he gave me a deal I couldn’t refuse 😂
It’s been on a Dynojet and it pushed 717rwhp/663tq on 93 pump gas with 14 pounds of boost from the 2.9 Whipple. The engine has been entirely forged by a builder locally and then everything was dialed in over at Premier Performance down in SLC. It’s on the stock heads (although I think they have been modded in some way) as well as the original WAP block.
I’d always heard folks say that the TEKSID block was the only way to go (and I know it’s a great block) but it seems the WAP block can handle some power too. This current engine build has barely over a few thousand miles on it. It’s terrifying to say the least.
My biggest issue with the car currently is to get the front coilovers squared away, they make all kinds of popping noises when turning (I think they might be missing the bearing that goes in between the coils) as well as the fact that it scrapes everything. I’m going to see if maybe the rear coils need new isolators….maybe raise it up just enough without changing coils (Eibach Sportlines is what it has).
As for the Azure Blue, it needs freshening up….it has 128k and it’s all stock. It lived the life of a daily driver that was never garage kept. The suspension is TIRED. Some other things need changed to make it smooth again too……but my goal is to get it back into fighting shape and cruise it. Cheers Mike and thanks for all that you do. I look forward to seeing your big garage once you get it built.
@@keystonekrawler6242 Thank you very much and thank you for sharing about your cars. Looking forward to future updates!
Which is the better engine 01 4.6 or the 03-04 mach 4.6? Or i guess the question is what the differences other than different camshafts
Very good question. The 01 Cobra was 9.6:1 compression where as the Mach 1 was 10.1:1. Because of that the Mach one had slightly more torque, but the Cobra had more horsepower on the top end. Between the two the 01 Cobra engine is slightly better. Which car was faster? Stock for stock the 01 Cobra beat the Mach 1 in 0-60 and quarter mile times.
@@MikesGarageRoute66 i thought the mach 1 was faster 0-60 as well as quarter mile for the simply fact that the cobra had a higher gear ratio of 3.27 vs the mach 3.55? So the mach and cobra are virtually the same car other than the IRS on the cobra which some prefer and some don't. Love talking cars thanks
@@stephencarbajal5657 From what I read the Cobra was slightly faster, but honestly it was a drivers race. The Cobra had 15 more horsepower then the Mach and was about 10 pounds lighter. Both great cars. I just wish the Mach 1 came with amber tail lights. That would have been nice 👍🏻
@@MikesGarageRoute66 yea i just turned down a 01 cobra because I want a mach 1(the cobra has the amber tail lights) i just think the mach is really unique being on how Ford designed the shaker hood scoop but it's hard finding info on the difference between the cobra and the mach.
@@stephencarbajal5657 They both are really great cars. Either one is a good choice 👍🏻
Hey Mike: I know there was no chocolate cake or anything but still a good vid. Quick question. I have a cherry 03 Marauder. I've done some things but primarily for my question I've put a 4:10 axle in and Mo's Tune for 93 octane. What's your best guess for power increase? I think 15 hp perhaps. Also you might want to mention about TSB 03-5-5 about the axles in Marauders. I used to see them at the dealer getting the axles replaced for that TSB. Actually it was all the Panther platform cars late 02 to early 03. Insufficient lubrication it said. Both the axles on my Marauder were going south when I got it. So it got new axles and a 4:10. What do you think about the cooling system mod. for the back of the heads?
Thank you for watching and it sounds like you have a nice Marauder. For the head cooling mod check out Cobra Engineering or Wonder Racing. Try to stay away from MMR. Your car probably gained 10 hp. I’d recommend doing an Eaton Swap. With a 4:10 gears and an Eaton you will be amazed how fast it is. You should check out Z Man’s Marauder.

Thank you very much. I really appreciate it!
04 mach1..vortech e trim 440 rwhp on stock motor.had this setup since 2009..still running strong 38k miles car is a blast to drive still holds it's own on the street..do u think I can go alittle higher in boost and do alittle over 460 rwhp and still be safe?
On a Vortech you can turn it up a little more, just keep the timing around 13 degrees at WOT and AFR between 11.2 and 11.5:1. I would keep it under 475hp.
@MikesGarageRoute66 if I wanted to open the motor up and forge the internals.what is a good setup? Just looking to go up to 600 rwhp..good street set up and reliable
@@billybrower750 To be honest, I wouldn’t. Very few of these “built” engine survive more than 10k miles. Most people don’t know how to build them right. Including the builders. I would focus more on weight reduction and a better gear.
Thank you 😁
Thank you for watching!
So I have a 04 mach 1 with a 122k miles and I really want to boost it, what all would I have to change/refurbish for a light boost set up talkin like 5lbs and would the cobra Eaton supercharger bolt up on it? Thank you
The Eaton swap will give you 8 psi. The easiest to install would be a Vortech or Procharger.
@@MikesGarageRoute66 how much boost would you consider reliable on a stock motor mach? been seeing people say they spin a bearing at 450 whp
I have been watching a lot of videos but this far the best one.
I have a 1999 cobra and I’m planning on doing a twin turbo on it. My question is what should I do the motor before putting them on so I don’t blow the engine, I only want to get 750hp to 800. Thanks
Thank you for watching James! On the 99 cobra I would do the following: Manly, K1, or Molnar Power Adder Rods. Pistons need to be made out of 2618 material. Pick a vendor but ensure it has a coated side skirt for longer life. Also the farther down the top ring is the better. Wiseco are the ones I like. Compression depends on your fuel type. E85 do 10:1, if you need 93 octaine you will have to have the compression much lower and HP will be limited. Besides that new bearings and upgraded oil pump. Have the heads refreshed but unless you put in higher lift cams you should be good to go. Just do the head cooling mod, not the MMR one...

What do you think of these numbers?
Hey Mike!
GREAT video! I am looking at buying a 2003 Aviator for a donor motor for my 04 Mach 1 (manual). Is the 6 bolt crank the only difference I should be worried about??? Could I just buy a new 8 bolt crank for that block?
It is the only difference. I believe you can get a 6 bolt flywheel and you should be good to go. Just do a good once over of the engine, change the oil pump and double check the pickup clearance. If the tensioners or guides look worn change that as well.
are 03 Navigator heads different?
Navigator heads are the exact same. Thanks for watching!
how much life would you say is left in the pistons of a 130k mile cobra engine thats been properly maintained? and what will the wearing on the piston skirt/ ringland actually cause ? just more oil consumption? smoking?
Thank you for watching. With 130k you may notice more piston slap when cold, the rocking motion accelerates the wear on the piston skirt and ring lands. Symptoms can be oil burning, but that can also be oil from the valve guide seals as well. The best way to check is a compression check. If the difference between the highest and lowest cylinder is more then 10 percent, then the lowest cylinders are weak. You can then put a little oil in the cylinder to see if it jumps up, that means rings if it does. An alternative is a leak down test. Chances are with 130k miles a compression check will show the engine has some age.
Lower compression ? Possibly. Always have a compression test done. It will tell you if its time for a rebuild or not.
Are the rods/pistons the same from the 2v as the 4v? Wondering if I can put the Manley rods/pistons I have from a 2v in to a 2004 Mach 1 engine
Yes they are the exact same. Thank you for watching!
@@MikesGarageRoute66 thanks for the help!
Was that auto cast cranks 6 bolt?
Yes the cast crank was 6 bolt vs the forged Kellogg crank that was 8 bolt. Thank you for watching!
@@MikesGarageRoute66 my 5 speed mach 1 has the engine replaced before I bought it. But I didn’t know that for almost a year after owning and I went to change the clutch and found a 6 bolt crank lol and 6 months later it started knocking. So now I’m sourcing a navigator 5.4 and a replacement!
@@sidsideways2828 Wow that's interesting. Sounds like someone dropped an Aviator long block in and flipped it. Very sorry to hear. The 5.4 would be a nice swap.
is it not true that the 03 04 mach 1 manual trans came with forged rods and the autos didnt? read that somewhere
The manual had a Kellogg forged crank, the auto had a cast crank. Both engines had the same weak rods that were in the 96-01 Cobras, Marauder, and Aviator. Only the 03/04 Cobras had Forged Manly rods. Thank you for watching!
