When were Corvettes allowed to race in modified stock? (ss/as.bs.cs etc)
I know the NHRA rule book used to state it was for 1967 and up production 2 door sedan or hardtop passenger cars. I checked the 2013 rule book and the sedan and hardtop statement is absent under SS but is still there in Comp. I am asking this because of a certain Corvette that usually runs IHRA PDA-1 , ran SS/BS this weekend at Norwalk. This is the first time I've seen a Corvette in Modified Stock and I thought it was BS.
