Is my crank drilled for a 4 speed?
Mine had a bushing in it as well. But the OD of the bushing was smaller. There used to be an undersized crank bushing to be used with automatic cranks that were drilled, but not honed to final size. I couldn't find one for sale anywhere, so I ended up using a pilot bearing that fit into the torque converter register.
I believe my crank had an ID of about .910, and the bushing is like .960 or something close to that.
