Not only were the 1111480 distributors cheaper direct from Delco, they were still available after Chevy was sold out. (I was working for a warehouse at the time.) The last one I got from Delco was a restamp from the factory. Sold it in the blue stamped Delco (not a label) box as a core last year. I also had friends at several GM dealerships that were on different inventory systems who would give me a copy of their printouts or let me search on their computer system. I used to pull obsolete parts from dealer stock all over the country. Could buy Holley carbs cheaper from Roy Johnson than we could get them direct from Holley too. Not many people were aware of the date stamps back then either. Wish I had it all back to sell at todays prices!!
