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
