What year 302 will fit in my 67 mustang?

 

cmiir, All 302's can fit, EFI Engines take a lot of mods,
not sure what year EFI was used, but pre efi is purely bolt in if the car was already a v8. if it was an i6 thats horse of different color

 

any year will fit.

like joe said though, the EFI will be harder if you want to run EFI, but if you want to stick carb and you get a EFI motor just change the intake, get a carb, and maybe a distributer? and you should be good to go. as far as some other stuff as far as headers as some had heads that will need special headers, tell us what your looking at and we can help more
