I agree with Automotive Breath, put a bigger accelerator pump shooter on the primary side of the carb. May need to do this also on the secondary side of the Double Pumper carb, but do primary side first.. Very common problem and easy to fix on the Holley carb due to its modular design.
Carbs are virtually never right the way they come from Holley( or Edelbrock, etc), to many variables involved. They are set from the factory to basically get you running and it is your responsibility to tune it to your engine. This does not mean just turning the screws, it often requires you to change individual parts of the carb.
