Saying it's all about the amount of air is over simplifying things. DEPENDING ON THE COMBINATION, a smaller carb can ET & MPH better than a larger carb when it has better shift recovery.
That I doubt.
I had a 950 on my 318, local friends told me car would ET better with a 750. It didn't. Wouldn't run within a tenth of the 950. Brett and others on here said beforehand what happened is what would be the case. Me being hardheaded, I had to try it.
