I have a question I've been wondering about chiefly the A/stock cars in the 66-67 period. Somehwhere along the line(I think '67) I know the rules distinguishing SS cars and the 'stockers' changed, but I notice they only called the A/stock cars 'Top Stock' while the rest down to E/S as of '67 were called 'stock'. Were the A/stock cars at that time period still built by same 'stock' rules as the rest of the stock classes or were the A cars allowed more Super Stock parameters, such as any cam or intake etc. I notice in reading some denoting Stahl's 66 Belve A/stock car as an SS car. Just wondering because from what I have read they made it sound as though the A/stock cars were a class unto themselves at that time with different build rules than the rest of the stock class cars. Fred you ran stock class cars back then how did that work with the A cars?
