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

Comparing diameter is the only way I would know of. If it's undersize YOU NEED TO CHECK DEPTH. Only way I'd know is find someone who can provide "figures" ..........the depth from engine bell surface to end of transmission shaft, then justify that from the engine bell surface to bottom of crank hole.

.........or.......jig the crank up in a block.........install a bell.......and then measure the the transmission mount surface to bottom of crank, and compare to your gearbox shaft length
