Your beloved 1960's and 1970's stockers are far from stock as new cars. Old combos are as much of the problem as new combs.

You're right that stock doesn't have nearly as much stock as it used to, but everyone has aftermarket pistons, rods, valves, cams, etc. Those rules are the same for all combinations, and it's a lot different than completely replacing an intake with a much better one, a completely different carburetor that flows 1.5x or more what the old one did, and a cam with larger lift. 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.

Is the case being made that the parts in question are correct and backed up by legitimate sources, or that 'other cars have illegitimate parts and therefore it is ok'? Or is the argument that parts are unavailable and superceded parts are deemed necessary? If the latter, parts with improved performance capabilities should carry additional horsepower, as has been done with some aftermarket heads, etc.

It appears that it was an over the counter option that other makes of cars have got approved and I believe no different to what NHRA has allowed for use as applicable to the 1962 Plymouth with the 383 - Two/4BBL, another over the counter parts package and other allowances such as the aluminum intakes for the 273 Chrysler, Fords, Single 4BBl Hemi and many others.

Those cars SS also were built with lite valves and C8AX NASCAR mech lifter .600 lift cam

In my research it appears you need to go find any dealer performance catalog from any manufacturer and get approved whatever parts were sold over the counter. I dont see why the stretch is not made to put the cross ram on all amc V-8 engines because it does not specify what motor it goes on. Stock is nearing its end and like i said i am going to complete my bucket list before we are merged into some other grand plan.

These changes are making Nostalgia SS look better and more legit all the time

Stock ended over 27 years ago anyway. Why all the bitching?

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!!!

Isn't it amazing that the guys that are complaining the most, are GM guys and it is them who have been the benefactors of probably more rule changes and superseded parts as anyone. Remember unported heads and no combustion mods in Super Stock? It was the small block Chevy racers that pushed the rules as much as, if not more than anyone to get the head rules in Super Stock changed. Remember when Bowtie blocks with siamesed Cylinders were legal before anyone else could use a siamesed block? How about 327 intakes on 283's or how the small block Chevys were mysteriously allowed 550 gram connecting rods when the old spec was 570 grams? I am not an AMC racer but I think it is about time that they were allowed some enhancements that some of the other brands have been allowed. After all, isn't the AHFS supposed to take care of any runaway combinations? This is pure speculation on my part, but just maybe the NHRA tech department has gotten tired of all the GM guys complaining about every little thing and decided to really give you guys something to complain about. Or maybe the tech guys thought it would be nice to see something other than Camaros in Stock and Super Stock. Hey GM guys, keep complaining because it is helping the AMC's,Mopars and Fords and we need more of those brands in Stock and Super Stock.
