You really don't have to look any further than the pure stock drags and come to your own conclusions.
Once you attend a few of these things, understand the rules, and build and race a car for it, you'll see which cars are the more advantageous packages and which are "lacking" performance.
Given the fact that the cars all follow the same rules, and run on the same tires, it's really the only true comparison nowadays.
For those that don't want to research, the ram air IV cars (including the A-bodies) consistently put up quicker ET's and higher MPH's than the few HO cars that participate. That's from what I've seen in person and participating myself.
Alot of that has to do with the more radical camshaft the IV's get right off the bat, coupled with more compression, they make power, usually in the ballpark of 400 rwhp on a chassis dyno when tuned and tweaked.
The HO cars lack a camshaft and compression, but they do make a nice torque curve. But with the tires being an equalizer so to speak, low end torque isn't necessarily a good thing. They do however put up very respectable times.
