You've expressed the issue very clearly because I don't think it should take this much force to get the distributor in.

If it was too far one direction the dist would drop in freely and the gears would not engage correctly, but you would seat into the oil pump. That would probably result in the dist not turning though. If it is shimmed too far the other direction it would wedge the dist gears tightly and possibly prevent the dist from dropping in deep enough to engage the oil pump shaft. Of the two, that sounds like the more likely scenario.
When I did have the distributor in it was rotating as I spun the engine and the oil pump was not spinning. The tightness begins just as the gears start to mesh.

Both Rick and I have looked and we are not seeing any deformity or blockage. We both used a pick and screwdriver while inspecting and there isn't anything obvious. I started disassembling my points distributor so that I could try fitting the shaft. While I got it torn down quite a ways, I could not drive out the pin. Does anyone have a dizzy shaft that I could borrow to confirm the fit to the oil pump? If the shaft fits, then I would know that I have to look more into the camshaft alignment.

I was hoping to avoid having to do this, but if it is needed then it will have to be done.

I gave this a half hearted attempt and there was no movement. I'll give it another go this evening to see if there is any movement.
