75' First year on one A/SM . 10.5 lbs/ci

76' A,B,C. A became C at 10.5, B was 9.5 and A was 8.5.lb/ci

Changed again when modified eliminator was shut down in 1981

Today, there is A thru I/SM in Comp and is entirely different.

However, modified stock is similar to the old SM rules ex.SS/AS is 8.5 with 1 carb.
