Default Re: COPO part #s and a 9"

I asked this question @ SEMA last year. and BOTH NHRA AND GM both said "NO WAY!!!!!" The only way you get to run the "GM 9" is in the new cars ONLY. I spent over an hour talking with nhra tech there and gm people arguing my point and both agreed that this is an exception to the rule. Their logic..... "want to use the new parts ..buy a new car!" The same thing applied to the ford racers over the aluminum 9" center sections. You can ask Ken Meile and Rusty Hall how that turned out.
