Ram Air IV versus 455 HO

From talking to SuperStock guys, those Ponchos seem to do things kind of bassackwards of a Chevy.

As far as what makes them go or special tricks?? Most engines regardless of brand respond to mostly the same things...which is the right combination of parts. And careful building techniques, I am not sure what you guys think makes an engine tick. They all are just blocks, heads, intakes & exhaust and camshaft. Air pumps if you will, the more efficient you can make any brand the better.

I'm a page late, but better than never I guess. What I meant by "bassackwards" was that from what I've read and what the Poncho racers have told me is that in the Stock/SuperStock ranks have to take a different approach than you would with a Chevy. With a Chevy you can let the engine accellerate the car, which gives you the "mechanical advantage" of running your typical loose race converter with some steep gears out back...quite the opposite with the Pontiacs. The Pontiac engines don't like to accellerate as well, so they've got to get the revs up and "hang them up", as they say, using a tight converter and geared down out back. Therein lies the problem, as with most cars you run 5.13s or whatever with a loose converter, and you gain a mechanical advantage with that...you lose some of that on the Pontiacs because of the converter/gear setup.
