I've not messed with the HEI personally, but your symptoms point to a component break down to me. Here's a pretty comprehensive article on the units - http://www.crankshaftcoalition.com/w...ributor#Module Lots of guys opt for buying a new distributor vs tearing into it and replacing parts. Maybe Dave Severson or one of the other guys can chime in here?

Well I didn't have time to replace the module but I did get it out. I will get one tonight and change it when I wake up in the morning. I am going to go ahead and take the carb apart. It may not need it but it will be a good learning experience and who knows if any paint got in there from the air cleaner spacer. I will get it all put back together tomorrow and give it a test run. Wish me luck. And again thanks to everyone on here that has commented. I am a member on a couple other forums and nobody has given this kind of response on either of them.
