What is your fuel pressure psi? It should be around 6 psi for a holley carb.

 

it is set at 6psi

 

Did you plug the vaccumm hole right underneath the carb on the right side?

 

Adjust your idle mixture screws on both sides of carb for low rpm.You may have to change jets for high rpm and adjust accelerator pump if it stumbles at initial acceleration
