Cam - Head - 470 Selection

Read Andy's book more - and then a second time.
I'm not sure why the 550hp level, but to do it you have to give it air and rpm. I think larger MW cross section heads would be a mistake given the autocrossing and street cruising. You only need 280-290cfm and that can be done with good value on a standard wedge sized port. Get Stealths or RPMs with a CNC port or good hand porting to get you the flow you need. I stay away from hydraulic rollers, and any solid rollers get bushings. So at this point I would go with a solid flat tappet matched to whatever head package you end up with.
