I currently have a 91 with a I6. The motor still runs good but with 121k Im looking at doing a Chevy V8 swap. I was wondering if anyone knew of either threads on here or other websites that help me with exactly what engine, trans and t-case to start looking for, along with all the snall details like linkages and electrical stuff. Any help would be great.

Thanks, I just found that as I made this thread, any others places to look?

You can always use an S10 tranny, they use the same t-case (np231) as the YJ. and the s10 tranny bellhousing bolts right up to a chevy V8. Ive seen it done before.

Good to know, adaptors to the np231 are like $450. Is there a reason why people hold onto the 231 insteal of using a GM t-case? Are the D-shafts on the wrong sides? Also it seems like the 700R4 is a good choice for a tranny......Ill have to keep on reading, so many things to know. Although I am relising chevy stuff is alot cheaper and easier to find then jeep stuff

He's right. Not only have I seen it done....I just finished doing it. Very easy, IMO.

I didn't cover the small deatails in my thread, but I'll cover some here for you:

ALL Gen 1 (1955-1997) Small block Chevy engines share the same architecture. Meaning, they all look the same, parts are interchangable (for the most part), and they all have the same dimensions and bolt to the same bell housing. All SBC blocks from 265 CID up to 400 CID.\

It really doesn't matter what application you pull an engine from. Mine was from a '77 Caprice. But it could have come from anything. Get the ENTIRE engine assy; Water pump, pulleys, intake, carb (or EFI), harness, manifolds, alternator, PS pump, distributor...everything. Get it LOADED. Then you just drop the entire package in, as is, and hook stuff up.

There was a switch to a one piece rear main seal in ~'88. From that time on, the flywheels are different; they have a smaller bolt pattern, and a counterweight cast in.

Email me or PM me if you have more questions.

I am wonderring about the Chevy t-case as well.

I have a 77 blazer that I am wanting to gut and put the 350, transmission and t-case in my 89 wrangler.

Can I just bolt it up?? Or do I need to get a t-case from an S-10??

Thats all good and dandy, but youll have to fab up a cross member to hold it all in and youll have to change the axle in the front because the the D-shaft comes off the passenger side on the FS chevy where the d-shaft comes off the drivers side of the t-case on the jeep. You can use the jeep t-case on the FS chevy tranny, but you'll need an adapter.
