carb. crazzzzyness!!!!!!!!!

Little more info. update on my car. It has a manual choke with a stock convertor and the gears are 3:55 sure grip. I don't understand the recommendations for the higher cfm carbs when from factory this 440 came with a 650cfm i believe from my homework. I do believe this carb. could be tuned to my likeness but from talking to Holley tech support these double pump carbs could be very difficult to tune if not experienced. I would be more than happy to have someone look at this car for me with more knowledge than myself but as of now I haven't had any luck here in my area finding anyone. I live 5 mile outside of Irwin Pa. 15642.

I did check for vaccum leaks and didnt find anything so far. I did spray around the base of the carb with no difference in anything. The fuel pressure at idle is in between 5 or 6. Im a little stumped with checking the timing, Thats getting past my strengths so i prefer not to mess with that if i can.

I understand the rough idle as you stated and i probably am asking for a bit much cause its not that bad and doesn't idle rough at all after its warm.

Thanks for all the advise so far. I'm trying to addapt it all into my next steps.
