Well thank you, all. What it was, was, I finally loosened the spring type distributor hold down clamp and a piece of the collar thingey that the hold down clamp presses on fell on the ground, it had broken off. For some reason the casting just sort of fractured off but you couldn't see it because one of the arms of the hold down clamp was still holding it in place, sorta. Anyway, I went to the junk yard and found a distributor out of a '71 Nova and swapped points, etc. and put it in, timed it by ear and it does fine so far, without doing the hootchie-cootchie. Starts a bit better now and warm up idle is a heck of a lot better. Still wonder why the collar thing broke in the first place, but will keep my eye on it. Again, thank you all.
