how many zl1 motors were made

[Paul e]

It seems that there are more 3946052 ZL1 blocks popping up on ebay every day. From what I understood there were only 69 camaro's and 2 corvette,s and maybe 18 or so over the counter motors. And how do you tell if it is a over the counter motor from one that came in a car from a can am motor? I own one that doesnt have any dates or vin #'s on it, just a cast number. Mine came from Washington state and has a history of being in that state for at least 25-30 years or so.
