Hi,
I'm looking to upgrade my 86 442 (307) motor this winter. I already grabbed intake (A4) and heads (5A) out of a 84 Hurst Olds, but the donor engine had no OEM exhaust manifolds. I plan to use my existing 307 and rebuild the top end and keep the CCC, so I'm looking for a set of exhaust manifolds out of a 81-84 olds with the O2 sensor hole. So I have 2 questions
Does anyone have a decent set of 81-84 Olds 307 exhaust manifolds?
I'm up in the air on a new cam, so some input on a new mild cam or keep the original type 86 442 cam?
Kevin
