I know some of the older members (and knowledgeable younger ones) will probably think I'm we todd did for asking this question, but what is the difference between Yenko and COPO in terms of the first gen camaros? When I googled "COPO camaro" one of the first hits was yenko and vice versa. From what little I know, COPO's are still made and therefore a part of Chevy.... ? Was Yenko just aftermarket?
