to make a v8 work in your 95 car you would basically need everything from the v8 car. engine, wiring harness, ect, ect. It gets costly trying to find all the parts and pieces needed for the swap unless you have a donor car laying around. the rear end would be fine, as proven by my father the 7.5 rear can take quite a beating. I think just swappin another v6 in would be your best bet!
