I built a jig out of a piece of plate steel and a piece of thick wall tubing. I cut the plate to match the Muncie to bellhousing bolt pattern, drilled a hole that aligns with the centerline of the crank, welded the tubing at an exact right angle to the steel plate, then, I bolted the bell housing onto the engine, bolted the jig to the bell housing. I then inserted the drill bit into the tubing and drilled the tailshaft to the proper depth to fit the bushing.

I have drilled 7 to 10 engines with this jig (I even did one with the engine installed) I have never had an issue with it.

I just drilled the forged crank on a 68" Toronado 455 (on my Garage Floor, with out disassembling the engine) to put into my 64 F-85 .
