Still not sure what you're driving at here. The "funny car" reference?

The "recipe" you supplied for an old Pontiac is from the 1970s. Race gas and high compressin are for RACE CARS, not street cars. With that cam/head combination, the engine will make MAYBE 450 HP, be out of breath at 5,800 and in general, be a slug except in a light car with stiff gears.

Today, we take a completely different approach to building a powerful Pontiac. Porting the heads is paramount. The little intake ports are fine for a "stocker", but won't let a 455 rev.

While it may not be "necessary" to rev a Pontiac hard to make power (unlike the SBC), why not have "both"? It's nearly impossible to "tune" the low-end power "out". So, add parts to make it breath, and will make low-end power AND rev. Solid lifters also make a HUGE difference in performance. If the budget can stand it, solid rollers are "the best". Comp has some very nice "street" grinds in the XE series, just for the lower compression and higher revs.

It's not uncommon at all, to have 550-600 HP and 600 lb ft. with 93 octane, under 6,000. How about spinning it to 7.500? WOO-HOO!
