OK guys, put on your electrician hats (electrical is not my strong point).
Took her out for a rid today. After initial start up and a few idle adjustments she seemed to be running fine. Went down to Keytone in the next town to get a can of paint mixed for the trunk. On the way there I notice the tach jumping a bit, but could not notice any misfire. Now on the way home (about 10 miles each way, all highway) she starts missing pretty bad. Tach is bouncing up around 6000 and then 8000 and finally goes limp pointing straight down. Thought I had fried it, but it cam back to life after I had to stop for a light and the RPM cam back down. Ammeter is dead center with no movement, but the volt meter is bouncing near 17v. If I add any electrical load like the fan, the misfire gets worse and if I put the headlights on, it almost flat lines. It seemed to get worse the longer I drove it and as the battery got fully charged. Now keep in mind, that I just drove it from DTW last Dec. (I know that doesn't necessarily mean much). Does this sound like a voltage regulator problem?
