crankshaft question

Most cranks that I have checked are drilled deep enough but you do have to check. The hole for the pilot bushing is most likely no sized though. I made a tool that locates on the flywheel flange that allows you to chuck the snout of the crank in a lathe and use a steady rest to support the rear of the crank so the hole for the pilot bushing can be machined to size. Most people use the late model truck pilot bearing that is a press fit in the torque converter locating recess in the back of the crank.
