Wow, interesting statement by DoubleVision. I always heard growing up and at street races, that bigger is better including CFM on carbs. Friends use to run a 720 Holley on a 289 Ford and the engine would run like nobodies business. I'm running a 650 DP Holley on a SBF that requires only 480 CFM, The engine runs well under all conditions. I did have to drop the jet sizes a bit but that was it. I get good mileage as long as I don't open the secondaries.
