Here is a topic thats probably been picked to death, read an older post on mechanical double pumper carb vs vacuum carb, made me question whether I'm running the right carb. I have a 68 Barracuda with a Holley 750 (0-4779C) mechanical secondaries double pumper on a 340 with 520 lift, 727 with 3500 stall, 3.91 gear, street car. Should this setup be running a vacuum 750, if yes please give me insight on why? and what difference should I except when driving the car with the this carb?
