Default 302 - 351 swap
I have a '92 F-150 4x4, SuperCab, Short-bed, 302 EFI, E4OD Automatic. I'm thinking about swapping the engine to a 351 from a 88-89 F-150. Can I just swap the engines, or do i have to swap trans out too?

Engine will bolt right up, just use flexplate from 351.

Ok, Thanks. So, I'll just use the intake and everything off the 351? What about the computer? Do i swap the computer?

yes, use the 351 stuff including the ecu, I forgot to mention, u might need the y pipe from the 351, its a little taller and wider and the 302 y might be a little different.
