With the Automatic, I had a 4cyl auto, I had to swap the bellhousing, and use a 12v 3.0 starter and flex plate. Also have to modify the back engine plate. I'm pretty sure at one point I remember reading somewhere that a 24v 3.5 bolting into a gen 1 required frame engine mounts to be relocated as well like mine required. You also need a BFH for the fire wall. With your swap, your starter will work and your bellhousing. Your fly wheel and clutch plate set up may be questionable but I honestly think it will work.
