As I recall the only alloy C.O.P.O. block in '69 was the 427 for the ZL-1 Camaro. (I think they only made 50 and I saw one for sale about a year ago for $50,000) Chris Barton 1995 540 6speed, (What? This isn't a chevy digest?) I assumed it was a C.O.P.O. block from the 69 production run (only sold for off highway use) >> ------------------------------
