Thank you so much I really appreciate all of the help. Sounds like the renix 4.0 swap is the way to go. Thx for the list jeepcomj that's what I needed to know. Also is there any other specific markers on the renix 4.0 cherokee other than the year and the H.O badges? Also I think I have 4:10 gearing. Should I change it to, and if so, what ratio?

Ok so there is no easy swap huh. That sucks. Any other suggestions. Or is the best solution to change the harness and the ecm with the engine.

Hello all I'm sure it has been talked about but I can't seem to find it. I have an 88 Comanche with a 2.5L engine with a 4 speed trans, and the engine is tired. So I was told if I get a 4.0L engine and the 5 speed out of a 87 thru 90 Comanche or cherokee then I can just bolt it in with out changing the harness or anything else. Is this the case or is there more to it? Any help would be greatly appreciated. Thanks

Where can I get an aluminum valve cover? I can't find them anywhere
