I'll bet your distributor drive gear is NOT engaging the oil pump drive.
With the distributor gear out you should be able to turn the oil pump tang
with a long screwdriver.  If not, the oil pump shaft is too tight in the
bushing in the block. If your machinist drove the bushing out, chances are
they peened over the bushing on one end or both ends. I just had this
problem a couple of days ago.  Drop the pan and remove the oil pump and try
to fit the shaft into the block. It should rotate easily. Same for the
distributor drive gear. Once you know those are free it should be easy to
drop the gear in. Note that it spins clockwise as it slips in.

Good luck!

Crisis averted.
After speaking with Dick Taylor and hearing that Bill W. had a similar
issue, I discovered through their wisdom that the drive gear will drop once
you rotate the engine/cam a bit, and indeed it dropped and all is well.

This is such a fine group of people, friends and helpers. Thank you all for
your past and ongoing assistance you provide.
