Researching Magnums for abodies

The jeeps (Grand Cherokee) have the starter on the passenger's side so I don't know if the engine would work with a stock a-body transmission. Maybe someone else can shed more light on this issue???

Nope, they won't.
Not unless you used the Jeep trans also, and then it would have to be a 2wd trans, different crossmember and driveline.

I'm not absolutely certain, but I believe the difference is the BELL and not the engine

What I've read "over on the Jeep / 4x4" forums indicates the Mopar / Jeep blocks are the same

We are of course talking about MOPAR engines and not the older AMC V8
