Never seen it, doesn't mean it's not so. Seems like different parts
of the country had different "standard parts" in the engines. Fer
example, lotsa 4 bolt 350s in MT, not so many in MA.
I have a cast 283 crank in my EFI'd 302. It's from a 67 though.
Funny stuff in 67, spin on filters, no internal vent canister, no
machining for crankcase vent tube, but only on some engines. I don't
know what the connection is, except maybe California emissions.
I've seen the notched 283 engines. I can identify the source of one
as a GMC truck.
Sorry, back to EFI...
