I'm contemplating doing an engine swap on my 77 F150. It had a 400 in it, that was switched out with a 351M a number of years ago, now I have a 302 HO EFI from a 1990 Mustang GT that I am thinking about putting in. From what I understand, I have the C4 tranny. Can I change the bellhousing on this tranny to fit the 302? Other than an electronic fuel pump and the obvious EFI computer, are there any other major issues anyone can forsee? Motor mounts I would assume will be different?

 

your truck should have a c6.frame mounts are same .just get 302 truck mounts for the engine.if your truck does have a c4 you can change bells.

 

How do I tell if I have the C4 or the C6 tranny?
