Re: Vortec Roller Block 383 Build?
450 hp should be easy to get.
The GM Hot cam would not suit your build.
Look at the cam they use in the ZZ383 it would be better.
Camshaft lift (in): .509 intake / .528 exhaust
Camshaft duration (@.050 in): 222'c1 intake / 230'c1 exhaust
I would use a 3000 stall and a Holley 750 Street HP
dont think its going to be 450 with that set up. iv got 383 with 11 to 1 comp, 555 lift 306 dur cam, dart pro1 heads 200 cc, victor jr and 850 holly only putting out 425 at flywheel
