The techs at Edelbrock were nice and helpful and even sent me parts to try for free but in the end they finally admitted these type carbs where NOT designed for performance big block Mopars...more for stock small block chebbies.
That is a ridiculous statement from the Edelbrock employee as a carburetor doesn't have a clue as to what is pulling a vacuum under it. Something was wrong with your carb, pure and simple.
I could give you a ride in my GTX as it will explosively break the tires loose by merely stabbing the gas pedal.
With either the 750 AFB (now on my Duster) I use to run, or the 900 CFM Thermoquad that is currently on it.
