Has anyone ever drilled and tapped the drive end of a stovebolt camshaft so the timing gear can be pushed on with a harmonic balancer installer instead of all the mickey mouse heat and beat methods that are sometimes used? It would seem to be a pretty good option, especially if the timing gears are being changed with the cam installed in the engine. I think I'll do that on the Frankenstein 216 I'm building so I can tinker with the cam timing between dyno runs. I'll add a thick flat washer and a tapered-head Allen bolt to retain the timing gear. That's one situation where a set of reversed bolts at the bottom of the timing cover might come in handy.
