Okay,
After extensive testing, the original symptoms observed seem to be down to a bad condenser, as a few have suspected.
I have the original ballast resistor reconnected properly (as before), the original coil, and a new condenser. Timed as best I could, then ran a few preliminary tests, described in the last few posts.
Had SWEET over yesterday and we really ran her through her paces. Multiple starts, stops, hills (including a 15% grade near my house), high speed and low. Zero stalls.
Right result, I think. I may still have some minor issues going on with my distributor, but I will run as-is for a while and see that she continues to perform well.
My sincere thanks to everyone for their input and aid.
Respectfully,
Jim
