According to my Sean Hyland book, it's better to use the one piece gear since it won't shred the key. However, the latest rendition of it is set up for the latest rendition of the trigger wheel so if using it on an older car, the trigger wheel needs to changed as well.

you'll need a timing cover and timing set. Most/all of the rest transfers over.

BTW... spare parts list: going to have a set of ported RR adapter plates in the next few days, also have a set of coated FRPP headers.

nope,
its a 10 spline in and a 28 spline out

Unless its a T-56, then its possibly a 28 in and a 31 out or a 10 spline in 21 out.. Unless im wrong... someone please correct me if i am

Don't buy cams based on lift as lift means very little to making power in a 4v; duration is far more important.

The FR500 cams have more lift than the GT cams but they come only in the FR500 cam kit (springs, followers, cams, valves). The GT cams have less duration than both the FR500s and the 96-98 cams, which would be a far better choice. (the 96-98s). However, all of these cams are too short on duration for a 5.4. A 5.4 needs a set of cams with at least 220 degrees duration, anything less and peak power will be low and occur at a very low rpm. 360rwhp without long tubes is achievable. Torque would be in the 350 range.

The exhaust ports do not need to be "raised", they only need opened up a bit and and both the intake and exhaust need a good bowl and short turn cleanup.

This link will give you more information on the 5.4 4v swap than you'll ever need: http://forums.corral.net/forums/showthread.php?t=867886

Without a doubt, delete the IMRCs.

no... that's the output shaft on the trans and the slip yoke on the drive shaft.

300 for the plates shipped. for my shorties... 150 shipped.

IIRC it's 26 in and 31 or 33 out on the t56's. otherwise looks right to me.

You can use your 2v computer to control it. MMR makes a TB adapter so you can put a cobra TB on it and you are off to the races.

You can use the gears from a 5.4 truck engine.

gotta love it and you can get adapters for LT headers from Logan Motorsports.

I was under the impression that 3v swaps also required lengthening of some of the wiring harnesses..

Ah. So is the 3v swap "worth it" then, considering the fact that the parts aren't that much more? Obviously the HPS intake won't fit, but I recall someone saying that Bob might fab one up eventually.

Screw doing a 5.4 swap.... THIS is what I should put in my P71

How much more of a PITA would it be to throw one of those bad boys in?

that is in the plans as far as I know, though it'll be intended for 99-04's. Still, the 2v intakes have to sell quite a bit more units first (just to make back the investment). It makes for a nice upgrade for us 2v'ers down the road though.

the v10 uses a balance shaft and makes a poor performance engine, aside from the lack of cams, headers and any sort of useful intake manifold.

Nevermind.. Found it. Stock 6.8 produces 305hp/420ft lbs at the crank. And I did find aftermarket headers for them, but they're only available as shorties. Not too many performance mods available, but it would still be pretty good with a bore and higher comp ratio. You're right about the intake though r3d.. Would have to be custom, otherwise it wouldn't fit under the stock hood. I'm sure they're are probably a million other issues as well. I do recall seeing a V10 Mustang at some point though. Wonder if they'd care to share how they did it..
