It's obvious stock has progressed a lot, but my car still has the heads that came on it in 1970, same with the untouched intake manifold, type of carburetor (yes it's an aftermarket one but the same design), etc. None of the new cars are as close to stock as mine, although some are close just with messed up HP factors. Even the ones like yours, essentially the motor that came in the Mustang GTs before the 5.0, have more compression that the stock ones.

I'll agree with much of what you said here Andrew, as long as the slower half of Stock isn't included with that, because I think the slower rollers are much more stock like than the faster half of the category...one glaring bit of proof; I don't see slower rollers with wheelie bars, or a mention of Cal-tracs on them. Furthermore, I think I can safely assume that the major percentage of engine parts on all fwd combos are stock (only the camshaft and needed supporting parts are aftermarket on my car)....I think that applies also to the R/S(A), and lower classes too (maybe to some of the quicker versions of the slower roller classes)?
My car is about as stock as stock can get, which is one of the reasons I still dislike NHRA reducing the indexes .3 seconds, and changing our altitude correction factors to resemble the Super Classes. NHRA, PLEASE EITHER GIVE US BACK THOSE .3 OF A SECOND, AND/OR GIVE US BACK OUR STOCK/SUPER STOCK ALTITUDE CORRECTION FACTORS....THEY WERE MORE FAIR TO ALL CLASSES, AND TO RACERS IN ALL TRACKS!!!
