Carburetor cfm calculator

We all know a 750 is the best all around performance carb for a 340, 360, 383,4" sb's, mild street strip 440's etc and we also know they'll eat more cfm the more they're hopped up and rpm'd.

If its not hoped up...then they dont necessarily want that much.
A 318 ,stock cam n the rest..I'd use a 500 eddy. Stock 440 mild cam..Carter 625 is what I'd use. Set it and forget it.
The bigger carb is great, above 4500 rpm is when the 750 tops the 650. But if you have to have a shift kit...you will need to shift manually to even see that rpm range.
That's apart of why they ran them on 340's to 440's . mild shift kits hit at what 5000 rpm maybe , strip 5800 or so.. you get a valve body plate or complete and you'll 6800 rpm
I just wonder if the question is being pondered one dimensional.
"I can run 800, 950,1050 on mine" what are we talking about? A cruiser.
