Rules creep has always been a factor in class racing. Remember 1973 when NHRA made a big change in stock classes, no slicks, iron exhaust manifolds, etc. because stockers had crept toward SS "territory"? It took a couple years back then to stabilize on headers and 9" slicks, but by now stock is nearly what super stock was in the 1970s, and SS is close to Modified Production..
