428 with 390 gt heads? Ideas?
Hi i just bought a 65 f100, guy said it had a 390 and 4 speed out of a fairlane, while trying to get a clutch for it i found out he was wrong. turns out it has a 68 428 with 66 390gt heads, and with FE's I've double checked every number, casting mark, webbing, pulled pan and i'm confident with what it has. My question is has anyone heard of doing this and if so for what purpose? Thanks
