Carburetor cfm calculator

My GTS has a Quick Fuel 1050cfm annular 4150 style carburetor on it. This is a 9.5:1 451 with stock exhaust manifolds etc. with a Comp xe294h cam with 1.6's. It is every bit as snappy as the 750 for cruising around and if I'm going to launch it that's 4k and up so at that point it's a wash IMO. It took idle feed restrictor, transfer slot, air bleed, power valve and jet changes to get it right. It's pretty close in calibration to my old school 830cfm DP other than the main jets.
