any turbo sohc 4.0s out there?

Personally, I'd stick a single holset on the 4.0, but I might be a little biased towards holsets.

I don't know the 4.0 well, but I'd probably go with dished forged pistons, head studs, improved rods, a little porting and polishing, holset/fmic, 50 lb/hr injectors, and maybe a cam. I don't think I'd bother with o-ringing or lightening the assembly. Obviously you'll have to do something different with the headers/exhaust. If you can fab and tune, you can do it for a lot less than 6k.

but if you cant...its gonna be just about 6k (atleast thats what it is to supercharge)

I had to do it

"FROM HIGH PERFORMANCE MOTORSPORTS FABRICATION TO PAINT AND AUTO BODY I CAN DO IT ALL JUT HIT ME UP"

yes you can do everything except spell... lol. okay bad day is not better.

I want to 4.0 swap my 2.9 but i think it would be easier just to build my 2.9L low compression for S/C... any thoughts.. i dont even know what is entailed with the swap and if all the work is worth it.
