NHRA turned them all into Super Stockers. Any cam, valve spring, intake manifold, any tire that would fit the stock fender wells, As time went on more and more changes were allowed such as tubbing the rear fender wells, larger tires, roller cams. ported heads etc.
The stock classes were really STOCK with DOT tires (not the new sticky DOT type tires), OEM exhaust manifolds, a year limit (1960 and newer) No blueprinted cams, etc. and in the beginning the top class (A/S) was 9 lbs per HP instead of 8 lbs per HP.
