The camshaft will be in the ballpark of

327 / 350 hp cam

or something similar below

Camshaft Lift: .450 Intake /.460 Exhaust
Flat Tappet Duration @ .050" (222°Int/222° Exh)

Check to make sure the rocker arms dont hit the studs in the rocker ball slot at full lift if your using OEM or OEM style rockers.
