When your hot your hot even if the pump drive is not

This would be awesome to find out, I know I have at least one extra LA dist drive gear lying around, I'd need 2 for a proper test though to see how much torque it takes to break the tip off an untreated one vs. a heat-treated piece. If I can't find a second one I might try grabbing one from the junkyard next time I take a trip over there.

Has anyone actually tested how much torque it takes to break the tip off the oil pump drive shaft?

If you do this (which would be interesting), then FWIW I'd suggest:

Make 2 fine marks parallel to the axis of the shaft near both ends and aligned with some sort of pointers to reference both marks (like a timing mark pointer)
Apply torque in gradually increasing increments
Release the torque after each increment and check to see if the marks are still aligned
Once you reach the torque level where the marks are no longer aligned with their pointers when the torque is released, note that torque level, and if 1 or both marks are out of alignment. This is the tensile torque, which is where permanent deformation occurs and would be good to be able to back compute to the tensile strength of the material. Knowing if one or both marks has gone out of alignment will point to where the shaft is starting to fail.
Then torque as hard as you like, even to breaking
Of course, you should make a jig similar to the bushing in the block to help avoid bending of the shaft while you apply torque.
