I am currently building a new motor for my 69 Chevy stepside and would like your opinions and recommendations.
454 2-bolt (bored .060, honed with torque plates and align honed). 049 heads pocket ported with Manley Street-Flo valves (2.19 & 1.88) 4 angle valve job, matched intakes, polished combustion chambers and exhaust ports). Cast crank and rods (polished and shot peened with ARP wave-locs). Speed-Pro forged pistons and plasma moly rings, Clevite 77 bearings, Melling high volume oil pump, Cloyes double roller etc. The engine will be balanced and bluprinted. I have chosen a Crane flat tappet hydraulic cam 226/236 @ .050, .533/.554 lift and 112 ' lobe separation (not installed if someone has a beter choice). I will run an RPM AIR GAP and an 850 Demon carb with vacuum secondaries and annular boosters and 2" headers with dual 2 1/2" exhaust system. The truck has a 12 bolt rear with 3.73's and a locker. I will run 275/60 or 325/50 drag radials a built turbo 350 or 400 with appropriate stall converter. I figure the truck weighs 3,800 to 4,000 pounds. I am hoping to make 500 HP at the crank and run in 12's. I have a super power shot nitrous system if needed for more HP.
