GM officials have no say in the matter They submitted the new car to NHRA and NHRA allowed it in Stock which means they abide by the same rules as any other vehicle...I have never seen any separate rules governing COPO cars, have you? A flat refusal to allow the new housing would require NHRA to re-write the rulebook and put them on very shakey ground in their argument. Do you believe a swap of their current housing to a 12-bolt in the new car would be illegal?
