On first impressions of what you say it's doing, it sounds like a vacuum leak. I had a hesitation like that on my first car. It was a 1958 Chevy Biscayne, with a 283 and a quadrajet. The carb gasket had a leak, which turned out to be an intake manifold problem not allowing the gasket to seal. Since you've got the new edelbrock intake on it, the intake should be fine. you may want to go get a new carb base gasket and try that. I'm not 100% on that, but it's a cheap start.

I can't remember and I'm in a bit of a hurry to go back through your thread, so help me out... did you ever do anything with your distributor, other than timing? What is it, points, HEI, etc? Did you replace any parts in it?
