Question: Can someone explain to me why there would be a A-22-9 casting date on the Iron 427 block in a 69 COPO Camaro that is original to the car and car was built in 9 (Sept) of 1969 ? I have seen 3 69 COPO Iron 427 Camaros built in Sept 69 with the original engine and with original docs and with the Jan 22 1969 casting date on block. Very late production cars.
