Double pumper, vacumm secondary, either carb with the right tuning/modifications can give you the ability to flat punch the car and have it perform. the double pumper will be easier to tune, but if you go to an nhra race, and go look at the super stock and stockers, you will see cars that will run all the way in the 9's with vaccumm secondary cars, holleys, afb's, quadrejets, thermoquads, and more. They all run well if you set the carb up correct. also a big factor is the motor needs to be set up right and matched with the right converter. sometimes the wrong cam, headers, intake, headers etc will have a guy work on a carb over and over trying to fix a problem. but sometime trying to fix a carb problem is like trying to fix a symptom, not the disease
