Sorry, forgot to say there are no vacuum lines connected yet. The carb I am using has no vacuum ports on it so the only port I have is the one on the intake manifold and it is blocked off for now. I normally do not connect the vacuum to the distributor until I have the engine running right. The car as it stands gets up to temperature and stays around 180 degrees, the timming is static due to the lack of the famous little ball and I have tripple checked the carb area for air leaks. It has a great idle at 800 Rpms and I can even go down on idle rpms to about 500 before the engine starts to shut down.

I know I am running 100cfm over the stock but I need that when the supercharger come on board. So if the problem is not solved, when the supercharger is installed it will get alot worst.

I will look at it today again and try to narrow down the problem area (if any).
