I will reply but there are others who will also.
I would look for a C30 truck about mid 80s for a 454. Dont need 4 bolt mains. Use the 236 peanut port heads with good valve job and some home made porting job. Concentrate on super slick exhaust ports. Use pistons with pop ups around 180 to 200 to bump compression to 9.5 to 10 (still run pump gas) Cam, run something around 262 to 268 with lift aroung .500. Dual plane aluminum intake and headers. Carb, no more that 750, good Qjet will do. Spin that up to 5000 rpm and it will make a big block believer out of you.
