304 w/ Cherokee 4x2

I usually ignore the "V6" when someone is talking about the AMC I6. It's sort of understood. Many young people (even some in their 30s) have never seen an I6, unless they are Jeep or some foreign car enthusiast (Mercedes and BMW still make I6 engines, maybe Volvo...).  All six cylinders to them are "V6" because that's all they ever see or hear about. 

In this case it was a valid question as the title says Cherokee which could be a v6 or an i6. We had a v6 5 speed one. We got burnt on it just as AMC was done with no recourse.

I've been looking into the same swap lately as well. I have a couple 360's and a Jeep 2wd Ax15 with internal slave setup. I'll be converting the trans to the 95+ style external slave setup as I prefer it. There is a lot of contradictory information out there. The Amc V8's being externally balanced is what causes the trouble. Most guys say your best bet is using the flywheel from the 4.0L motor (neutrally balanced) and getting it 'match balanced' to your 304 flywheel and then using the 4.0L starter. The V8 flywheel is said to stick 1/4" further into the bellhousing and interferes with the throwout (although some say they've had no clearance issues using the V8 fly).

Your friend didn't need a spacer between the block and bellhousing? Some guys say it fit no problem, others say that with the stock V8 flywheel it's about 1/4" too deep into the Ax15 bellhousing. Been thinking of mocking it together in my garage for my swap before I put the motor and trans into my car, to find any problems before it's put in.
