I have a mild/medium built 454 with a Holley 750 DP, what should the pressure be at the carb, on the guage? I have an electric fuel pump, and a regulator, but don't know what pressure I should be at. The car starts to break up at about 4,750 when held full throttle from a start, like it's starving for fuel. Just swapped out the filter, also it only does it when it hits 3rd(T400) first and second wind through with no hesitation.
