ID this stuff for me

I have a 318 poly engine

casting number found on the front right below the head "2264?70" with a big "3" above it. ? looks like a 3 to me but could be a 8


casting on the right side below the exhaust manifold "12 3 62"

engine had a fourbarrel intake

and big Holly carb with a stack of adaptors when I got it. casting number on the intake is "1619826"

I can’t read those numbers below that starts with a 1. might be the firing order, since I don’t see that anywhere else on the intake.

All four barrels are nearly the same size ports.
I found a 500cfm Carter that seems to fit it perfectly.
