Have just fitted motor to my Corvette,it is 383 four bolt,KB 10:1 hyper pistons ,hydraulic flat tappet cam at.050 duration 214/224 at 444/467 lift,Edelbrock performer heads with LT1 springs ,hugger headers through single straight through Lukey back out to two pipes,standard oil pump ,three core alloy radiator,Holley 670 street Avenger ,wieand dual plane manifold,recod t/h 350 with stage two shift kit 3000 hi-stall Hei dizzy.Running 255x60x15 rear wheels.Any ideas on improving cam and general engine performance? Cam does not have as much lope as hoped for but it must be able to supply vaccum for brakes and lights.

I’d guess somewhere around 500-600 horses depending on tune. I’m no engineer, but that sounds like a sweet setup. Have any pics?

500-600? Not with that cam. With a good sized cam, I could see 450 at the wheels possible, which would be around 500 at the fly. As it sits, maybe 400-450.

I agree, MAYBE 400-450 is pushing it with the cam.

Hi ,Im a newbe here and have always loved gm, about this motor, i have built a few, to get over 400 hp out of that combo you need a comp cams hydralic roller cam, about a 286 grind or better,will match the converter and make an easy 450hp with a good intake, like a performer air gap and headers, also a little bigger carb.
