Ok, I double checked my carb numbers and it is #4776-B = Holley 600cfm, mechanical secondaries & manual choke. Can someone give me the jet size, power valve, squirter and any other tech info.
I couldn't find it on Holley's website.

It is a 4 speed and the motor does not stall. When idling I'll rev the motor and does not instantaneously react to me depressing the gas pedal. It hesitates or delays for split second then revs correctly. It doesn't matter if I'm idling @ 800rpms or holding the revs @ 2500rpms and then depress the gas pedal to the floor.
When I'm driving and mashing the pedal from a cruising speed this delay/hesitation doesn't occur.
Float levels are fine...
