4.0 into 4.2??

Previously posted a topic in the CJ Forum that should have been under engines...I'll figure out how all this stuff works before too long.

'85 CJ-7, bone stock exc. 2" shackles & Skyjackers. Engine is 258 (for now). Nutter bypass.

why the hell would you want to convert the 4.0 high output into the 4.2? the 4.2 is older tech. while the 4.0 has more power dont let the extra .2 fool ya

Clint wants to put the 4.0 into a CJ.


This is supposedly not to hard to do. I think that not much needs to be done, and that you can use you current tranny. Se what Advanced Adapters may have to say.

Also consider the MOPAR MPI kit, while more tired than a late-model 4.0, my 4.2 dynoed 185 hp. Seems a bit high to me, but WTH. However, the kit may cost more than a decent 4.0 from a wreck.

I answered in the cj forum. It was quite a book. Hamy.
