Sounds like too much cam for the street anyway, but what heads are on it??What intake did you choose??Carb?? Manual or auto?? I f it is too much cam, you may be better off spending the $120 and getting a hydraulic anyway. Get the springs from the cam supplier.

BTW, our "A fuel" car ran a 396 with solid lift. .026" intake, .030" exhaust 9000+ rpm.
