Another Slant back from the dead

Red, blue, yellow, black... they are all pretty much the same motor. 13 does mean the 13th revision of the casting, but it doesnt really correspond to the casting date as it could still be a first year casting, but just the 13th revision/repair of a modular mold. when you got 30 minutes, get yourself a $13 Holley 1920 carb kit from Autozone and do the accelerator pump replacement. when they go out (after sitting for a while is what I understand) they start to squirt gas out of the bowl where it meets the venturi (see that little hole?) onto your hot manifolds, not safe. Seen it and fixed it in 30 minutes. I say keep the slant. They run great and run forever, and are a great motor for the narrow A. V8 swaps are a handful in these chassis, been there, done that too.
