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.
