Ok my kid has put a 454 in his 62 and doesn't want to spend a butt load of money on the hooker super comps as it seems those are the only ones that fit with a 4 speed.I have seen a 62 or 63 with a BBC in it before with manifolds but forgot to ask what they came out of before the car left. I know my 65 manifolds did not fit so has anybody here done this. Car is a plain Impala with the 454 and a m20 no power steering.
