I'm new to the FX community (just got a 45 2 days ago) and am in search for information about my car.
Is the physical dimensions of the 4.5L and 5.6L VK engines the same? I would assume that the 5.6L is just a bored and stroked derivative of the 4.5L. Is there a difference of heads used, or is the casting the same?
Since there really isn't much aftermarket support specifically for the 4.5L V8, I'm looking for 'alternatives'. And that leads me to the 5.6L. I know the JBA already makes a set of headers for the Titan/Armada. Since both engines are of the VK design, those headers should work, right? The only problem might be chassis clearance of the headers.
What do you guys think? Maybe this has already been hashed out??
please follow up on your progress.....
as for needed power, you're on the right track, i believe
(((perhaps you can testfit the RHS tubes on a wreckeryard motor???))) i think, if you know a few peeps, you can find one torn down somewhere....
ps- are they eq. length?? shorties?? replacing the cats??
pss- i think the 5.6 ( V ___?) is stroker VK ; the bore may be somewhat close (it is more trucky-torque making)
