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.

[@MikesGarageRoute66]

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!

[@thestigisme2349]

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?

[@MikesGarageRoute66]

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!

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!

[@canadianmarauder1923]

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

[@MikesGarageRoute66]

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!

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.

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.

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?

[@MikesGarageRoute66]

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. kzbin.info/www/bejne/bJfPg6eElrF5gKM

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?

[@MikesGarageRoute66]

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.

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.

[@apocalypseperformancetwcam8386]

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!

[@MikesGarageRoute66]

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.

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

[@MikesGarageRoute66]

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...

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.

[@MikesGarageRoute66]

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.

[@MikesGarageRoute66]

Thanks for watching. Depending on the area 16k to 19k

[@FLPLASTICSURG1]

Would using the camshafts from a 2005 Lincoln Aviator improve the HP/Torque in a 2002 Lincoln Continental?

[@MikesGarageRoute66]

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.

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

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 Eaton swap will give you 8 psi. The easiest to install would be a Vortech or Procharger.

[@ScoutsGarage.]

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?

[@MikesGarageRoute66]

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.

[@Deeznuts84356]

Lower compression ? Possibly. Always have a compression test done. It will tell you if its time for a rebuild or not.

[@jeffreystelling3395]

What's your opinion on a 4V from a 97 mark 8?

[@MikesGarageRoute66]

The Mark 8 engines are great to build. Very strong block. The rods and pistons are the weak link. Replace them and your good to go . Thanks for watching Jeffrey!

[@user-kg6ur5pe2l]

Would anyone know how much the crank on a automatic Mach can handle?

[@MikesGarageRoute66]

Great question. About 750 rwhp. The big killer for the cast crank is rpm’s. It’s best to keep it under 7k.

[@billybrower750]

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?

[@MikesGarageRoute66]

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.

[@billybrower750]

[@MikesGarageRoute66]

@@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.

[@justin.c_svt]

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?

[@MikesGarageRoute66]

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!

[@justin.c_svt]

Dang! Haha. Well I guess we know people have manual swapped an auto Mach 1 before too.

[@ccmustanggt99]

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!

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

[@MikesGarageRoute66]

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.

[@stephencarbajal5657]

@@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

[@keystonekrawler6242]

@@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.
