Re: ZL-1 stamping numbers
COPO, I will dig them out on the weekend. I keep writing them down, but I always forget where I put them. I don't think I had a date code on the engine pad. Porterfield showed me Chevy copy paperwork (now where did I put that) that showed my engine number was in the middle of a sequence of racing engines supplied in around 1971 ( I think ). Pretty sure date was not part of the numbers. Maybe that's what the 61A was.
Also were numbers like my 107 common to all ZL-1s. Whats your got?
