Carburetor cfm calculator

Dan the man said
I came across a couple of formulas for calculating carburetor cfm. And for a 360 with a max rpm of 5,500 they all showed a cfm rating of just under 600 cfm. Even with a mild built 360 which for the most part won't see 5,500 very often isn't a 600 cfm carburetor too small or is it? I don't want to over carburate but at the same time I don't want to under carburate either. Is it true that the smaller carburetor will provide better throttle response and low to midrange torque? I'm trying to learn as much as I can so when I start the modifications the package will all work together.

A spreadbore 650 pumper on a TQ intake can put an A-body in the upper-mid 12's w/a moderately aggressive cam without any "supertuning".
With the right setup, bigger carbs actually give a better throttle response, the larger primaries give You more per throttle angle. It's when You're WOT that low velocity can hurt "response", but with VS/Air-valve Secondary carbs, that should be a non issue. If You have a loose enough converter, You can go "too big" on a pumper & will no doubt pick up a bit of power, but a fairly wasteful way to do it.
