I have seen a figure of 600 for the L78. I would have to find out where I got that number but It was recently I saw it.
I remember thinking when I saw it that "those are rare"
Rich I just to bump things up another knotch, I read on the Automotive History site (take it with a grain of salt) that there were only 10 COPO's produced. I dont know if it was refering to a COPO RS/Z28 or all of them. I am trying to get a hold of the site sponsor to find out where the info came from See link
