Squarebores & spreadbores react totally different from one another, so they can't be compaired as equals when your talking CFM, its apples too oranges, you can always get away with a larger CFM carb on a given app. if useing a spreadbore over a squarebore, i'm just talking vacuum controlled units, not DPers.
