Puttin a EFI 351W into a 1990 F-250 that had an EFI 5.0/5spd. My question is....the 351W right now is hooked to an Auto trans.

My buddy swears that the 302 flywheel will work, but I'm convinced that it doesn't because of the 28 oz. (351W) and 50 oz. (302) balances. So anyone have experience with this?

If I do need a 351W flywheel, would one from a 4spd trans work, with the 5spd trans? I mean for the clutch size and ring gear tooth count.... Please help me out.
