Thanks for the reply. Those stampings must be on the bottom because I can't see any, I'll look next time I pull the carb. Yes p.v. Front and rear.
I bought this carb from a guy I knew back around '90. I was under the impression that it was not that old at the time and out if the box stock. Other than that all I remember was he told me it was an 830. I searched holley's web site last week and found an 830 with the 31 squirters f/r, 80 jets f/r, yellow pump cams, front on 2, rear on 1. This is exactly like this carb is so I thought I probably found the right list #.
