Regarding the emissions issue, if you search here on the site you will find a discussion about GM paperwork where they were trying to get the L72 certified in the Camaro for 68 to possibly be a COPO. I would imagine Pontiac would need to do the same thing. If GM certified the ZL1 for the Camaro and Corvette, I would think they tried to do it with the RA V as well. But proving a particular engine was put into a car at the factory, it would need documentation and accompanying codes or VIN. Even the dealer transplant cars(Motion, etc.) had the engines marked and documented. Like it was said earlier, it will be just as hard to prove it is a RA V as it will be to prove it isn't.
