I pulled vacuum on the FP regulator and it held like it is supposed to. I'm going to figure out what's going on with the timing marks even though 10 years ago it ran as is. I may swap in the 2 or 3 computers I have lying around. I may also take it for a ride and see whether it clears up after an hr of driving. I may need to take a set of plugs in case these get carboned up and leave me stranded. For sure something isn't right.
