Any Carb Gurus out there want to comment?

Elmariachi is right, set engine timing first then work on the carb. If this is a street car I don't think you are going to be happy with this cam. With that high of duration and a narrow LSA you have a ton of overlap which drops your vacuum way down. That being said a higher compression engine needs less total timing also, but there in lies the conflict, they need higher initial timing at idle to run, but lower total timing. This engine should be able to run with the initial idle timing at just about 18 deg. As you know once you are opening the blades into the idle transfer slots you start affecting adjustability. This is one of those case where an engine my benefit from a vacuum advance dist. hooked to manifold vacuum that is adjustable. I met two guys in the last month that have pulled their very expensive high rpm race type engine for a more street friendly engine. In the long run I think you would be a lot happier by changing the cam.
