Let's not forget that Pontiac used 750 CFM Quadrajets on their Sprint sixes that were as small as 230 ci in 1966. Suffice it to say that it was tuned for the application and not used "out of the box" but then,that should be the case for ANY carb,really.

If tuned correctly (perhaps with the aid of a good Q-jet book such as Doug Roe's) even the Quadrajet's 750 cfm is not out of the question for providing excellent power and drivability for our beloved 6's.
