"4150" is the Model

"6R 7950 B" will be the Carb Number

I'd guess "82657" is the list number (or part of it) but it seems too high, and "1530" is the date code (made on the 153rd day of either 1970, 1980, 1990, 2000 or 2010)?

I can't find that exactly carb number listed but best guess is that it's a 650CFM square-bore, mechanical secondary, double pumper, with no choke horn and idle circuits on all four corners?

The Holley book that I have was written in 1988, but it does have a few 5 digit list numbers in there. Just not this one. The closest is 83310 which is a vac secondary 750. A photo would help here.
