Hmm.. maybe I should have titled this "Hi flow heads + short duration cams".

Yes aftermarket heads are expensive, but for those that do bite the bullet, 300+cfm heads are not much more than out of the box. A short duration, hi-lift, low-overlap roller shouldn't be too hard. There are plenty of aftermarket fuel-injection systems, throttle body or port injection, or MegaSquirt for the more ambitious. Or a Q-jet to keep it simple.

Traditional thinking says big heads + small cam is mis-matched, yet that is what GM does now with amazing results, so why couldn't we do it?
