I should also say that the engine ran great with stock cam..good smooth idle, good vacuum, lots of low end. Its just now that i switched to the comp that i have started to have these problems.



First, that cam should idle much like the stock cam. Second, focus on the things that you changed. If you only removed and reinstalled the distributor and carb, I would not mess with them other than to make sure that you reinstalled them correctly. Challange and recheck your work that you have convinced yourself to be okay. I would start with looking for a vacuum leak. How did you check that the first time?
