Will my 390 in my 1975 1/2 ton automatic go in a 1970 f-100 1/2 ton automatic, the 70 has a 390 in it now. Would there have to be alot of modifacations? thx David

Since the blocks are the same, it shouldn't be that difficult. What's wrong with the '70 390?

yes it will go right in with no probelms or modifications. except maybe the exhaust.
