[COPO]

I don't have my #'s in front of me, so I'm going by memory. I believe there were 373 COPO 427 engines produced for '69 Chevelles of which about 323 went into cars of which 99 were Yenko Chevelles. The remainder were service engines. There were 69 ZL-1 427 '69 Camaros (aluminum 427) built and 100+ engines built. There were 1000+ COPO iron block engines (L-72) built coded for '69 Camaros of which 198 were Yenko Camaros and another 300+ in non-Yenko Camaros sold by various dealers. The remaining engines were service engines for warranty replacements. No one really knows the exact number of cars produced.
