Don't get suckered by boost numbers.
Boost is a resistance to flow. Good flowing heads and a proper cam will show less boost than poor performing components with the same blower and drive on the same bottom end.
I made more power at 8 psi with the Eddy heads and good intake than I did with the iron heads and Torker intake.
what he said...I love when guys talk about running this or that boost. It's just a measure of resistance, you want air flow. From what I understand those old Hemis like boost. A 671 will work, but an 871 will work better and w/ less heat and stress.
