Re: holley 750 D.P. carb jetting??
A 750 4779 carb runs best with right around 70 primary jets with a 6.5 power valve and 80 secondary jets and no power valve. You might have to go slightly richer and change the power valve to suit your cam but those are the baseline numbers I always used on a 750 dbl pumper. Accelerator pump squirters and cams is also abig part of tuning one for your application......
