I have a slight hesitation when accelerating from stop... Running at various higher  RPMs,  then hitting it....it accelerates fine only coming off idle does it stumble.    It's not a pronounced bog.  The engine runs good otherwise......  Could it be I need bigger squirters? idle set about 900.... .... Newly rebuilt Holly 780. ( yes it is the 780 / 3310-1)

I always wanted to be somebody...

I guess I should have been more specific.

Before you change everything in or on the carb be sure you have the correct jets and pv in it according to their specs.. Also holley jets are all not the sizes they represent, they have a correct jet size on their site.
