Mini, You are of course 100% technically correct. A car with a Needs Wings shouldn't be considered "stock". It's a documented fact that it alone will cut nearly 1/2 a second off a NA's 1/4 mile. (not sure how much on a SRT).
But essentially it's nothing more than a better executed air delivery system, with a less restrictive air filter, than what the very restrictive factory design offers..
40 years ago, you could run any type of air cleaner you wanted on your car at the drags and still be considered legal under "Pure Stock" rules. For the most part, everybody ran without an air filter element, or simply a velocity stack on their carb, just to smooth out the air flow. (Which the NeedsWings does so well). Some guys even ran 4" diameter cloths drier hoses from scoops mounted under their front bumpers (like the W30 442 offered) into their air cleaner housings, and track officials would let it pass in "STOCK" class.
Going by what I just said, I wonder if I went to the Drags now a days with this on my engine,

I wonder if the track officials would let me run "Pure Stock" class, if there even is such a thing anymore?
