Hello Friends: Here is my problem. I have a very nice Nova with a 350 ci engine, 350 TH auto, ps/pb/air. I have installed a moderate Crane cam and a Edlebrock dual four barrel intake with two Edlebrock 1405 (650 cfm) carbs with progressive linkage. I have difficulty with the engine idle and have difficulty with gas fouling the plugs at rpm. It seems to be dumping way too much fuel and I have leaned them out as much as I can (being I am not a carb guru). I really installed this set-up for the killer looks and not for performance. I had recently pulled the set-up and re-installed the Corvette dual plane and 790 cfm Q-jet, new plugs (again) and everything runs great, but the engine bay looks like the other kazillion chevy 350 out there.

Question: How do you tune the dual 4-barrel set-up for good drivability ? Is it possible ? If not, then this set-up is for sale. Thanks for your input.
