What would it take to get a 69 Chevy Step Side into the 12's, thats where it started! I'm on a budget and a big block project seemed out of reach, but after some reasearch and parts scrounging I decided a 454 and a shot of NOS should do it. Pat, John and a couple others have all had some great input and I welcome more. I have made one mistake so far, and am in the process of correcting it (to little valve to piston clearance). I am still stuggling with the cam I choose!. Here is project 454. MarkIV 2-bolt .060 over, line honed O decked, 049 heads w/ 2.19 & 1.88 Manley Pro-Flo valves, pocket ported, opened throats and unshrouded chambers, shaped the short side radius and cleaned up the ports a little (did not polish intakes or get to crazy w/ the cutters), matched intakes, polished exhaust ports and chambers, 4 angle valve job etc. Stock rods polished and shot peened w/ wave lock bolts. Cast crank, Balanced rotating assembly, Speed Pro pistons and rings. Melling oil pump and Moroso steet stip pan. CC'd heads and calculated compression to be 9.4:1. Edlebrock RPM Air Gap and a Demon 850 w/ anular boosters to top it off. MDS distribtor and 6A box. 125-150 HP plate style NOS system and 2" headers w/ X pipe or crossover, 2 1/2" exhaust. Last the cam I picked was a Crane 226 236 duration @ .050, .534 .553 lift and 112 degree LSA (this wider separation seemed to be better suited to the NOS). The truck has a 12 Bolt w/ 3.73's and a locker. I will run MT 325/50 Drag radials and a Turbo 400 w/ 2800-3000 stall coverter. Will this truck run 12's?
