I have the drivetrain from a 72 commando with a dana20 t case and the TH400 tranny (SBC and BOP belhousing pattern) that had a factory adapter (to AMC engines) and spacer for the flexplate. if you go the 4.3L route you will need something similar to bolt to the engine (besides 500$ AdvancedAdaptors units)
but i believe that the 90* 3800 (S1&II) all have the 60* belhousing pattern so it should bolt in place of a factory jeep 2.8L "rod thrower" GM jeep engine
the engine mounts will need work as with all the ancillary equipment required to run it (you can make a VATS Passkey simulator from radioshack components)
the flexplate should have the right pattern for the converter though
what tranny does the jeep have? what engine?

Thanks guys!!!! Now we are getting somewhere.
I have yet to buy the cherokee, I want to do my research first in order to make things as pain free ( I know, I know) as possible. My first choice is to use a 3800 "C" engine if possible. The only outside PCM input is from the VSS in the transmission. So this would be the least complicated elctronic assembly to install in a cherokee. Second choice is to use a 1995 camaro/firebird (3800) engine and transmission (700r4), this being a OBDII setup would require more electronic mods and a PCM/Memcal reprogramming making it more difficult once trouble arises on the trail. Remember the only purpose of this swap is ultimate reliability and easy, easy spare parts (junkyard) parts sources. Questions.

1 Anybody know of a web site that would clarify the 3800 "C", series I and Series II bellhousing bolt pattern. Is it the same on the RWD 3800 camaro as the FWD 3800'*??

2 Motor mounts, does the camaro/firebird RWD 3800 use the same block as the FWD 3800'*???

3.Could I put my 1988 "C" 3800 intake manifold on a series I or II 3800 block such as a camaro 3800 block?. (would allow me to use the simple 1988 PCM)

4 What was the last year of production for the cherokee to come with a 2.8 (rod thrower) engine and were they availible with an automatic trans.

I really appreciate any input you guys have to offer. I am slowly getting the details that I need to make myself the vehicle that I want instead of having to settle for whats availible.

Thanks Again
