My brother in law's race car has a cam with a .780 lift, the useable power band is 4000-8500 rpm. And no, it would not make a good street motor.

On a separate note, I have seen modest gains from porting and polishing heads on pushrod V8's and unshrouding the valves etc. Anyone ever do this to the already good flowing E46 heads?

I wonder if my local salvage would let me test on one and then bolt it to a festers car. I don't want to mess with my ZHP like that so if I can pull it off, who wants to have the head swap done?
