It is still a legal SS class and IHRA has one for Stock. SS and Stock evolved because of racer ingenuity and pressure. Even Pure Stock has morphed into Stocker Blueprint cam rule. Stock morphed into SS light with any Valve Spring and Duration rule. SS you can have ported heads...! What date do you put a "period" on for what you consider the purity of SS or Stock? Dan |
