Project 454

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.

I like everything you have there. I have a good friend that has used a very simular combination many times .You may find that you will need more tire and wheel to make it hook up:)

Sounds real strong step side. Give us some pics when ya get er going DH

Yep, that oughta work Stepside.

Stepside, sounds like a strong combo. Glad to see you're not going crazy with the cam like so many others do. I think that's a fine choice. I dont know if you'll hit 500HP at the crank, but you'll surely be very close if not there. What do you figure your compression ratio should be? I agree with the traction issue, you better start stocking up on rear tires!!!

Thanks to all who have replied to my message. The CR should be very close to 9.4:1. What do you all think this beast will run in a 1/4 (assuming we can hook it up) on motor? on the bottle? Thanks again!
