    MONTE CARLO Carb

    I have a 400pontiac with Holley 600 carb, Holley red fuel pump and a fuel regulator. The problem I'm having is that when I'm taking off from a stop it hesitate an I'm trying to see why. Do I need to go a size up on the carb, is it getting too much/not enough gas or.... Any thoughts or tips?

    I have a Pontiac 400 with 600 Holley carb; Holley red electric fuel pump; nitrous xpress regulator with gauge; and a as far as I know stock 700r4 torque converter. The problem I am having is that the brakes are stiff even when the car is running also I was told that the carb couldn't be adjusted...
