How to tell if 440 Chrankshaft is drilled for 4-Speed/Pilot Bushing??

So when I bought my "Running 440, doesn't need anything, maybe new rings" motor, the guy was full or crap. Heads were completely screwed, not a valve seal was complete and not one cylinder held any pressure. Frozen lifters, frozen wrist pins, etc. 6-pack was fort a B-block, not a RB, yeah, BS artist. Got me. It absolutely needed a rebuild.

Anywho, on the list of lies was that the crank was drilled for a 4-speed. I can't find any reliable info on how to check short of "buy a pilot bushing and see if it fits."

Can anyone tell from this pic (for sure) or tell me how to check?
