I don't know the answer, but here's what spooked/impressed me: I went to google it, and as soon as I typed "GM engine" the autosuggestion was "GM engine family 113" so I assumed I'd found the answer!

But alas, the pages that came up didn't really have anything to do with engine family 113, but the formulation (guessing) of my search intent was pretty impressive. Must be gathered from the page content, I guess.

I've got my original 1973 350 in the garage with the same casting number. That block was used in just about every Chevrolet car line and pickup and Canadian Poncho's. If its a 2bbl you have an L65, if its a 4bbl its likely an L48.
