If I understand correctly the car is being represented as an L72 COPO.
There is no way to determine this solely by VIN/tag info. Non-Yenko COPOs are predominantly Norwood-built, 03B and later. They were based on production SS/big-block componentry and all had the ducted hood. The only unique part other than the engine is the "BE" code rear axle.
There were also a number of dealer-conversion 427 Camaros: Dana, Nickey, Baldwin-Motion. Dick Harrell also may have done some. These were generally performed on factory L78 SS cars.
Either is easy to "clone". If there is no paperwork with the car to authenticate it as such it is nothing more than a 1969 Camaro.
