Earliest date of 1967 big block Camaro build...

I am still trying to locate the guys' name of the 4:56 geared L78, but have gotten the name of the original owner of the 4:10 geared car (Harold Bottoms..maybe his car is still out there in someone's collection???) I see the guy all summer at cruises, but for the life of me can't remember his name (twobryans you out there..maybe you know the guy I'm talking about???) I remember he told me it was at GM Carlise that he met Grumpy (maybe the same show from a couple of years ago) so maybe someone has pics, although not sure if he took his car or not. I'll keep trying to locate the guy and get his info. This is a neat topic.
