Re: Is a 750 carb too big for a 327?
Well like I just simplified the equation posted above, I am sure the 3456 is some formulation of air volumetrics, x Pi x the moons gravitational pull, etc, simplified down to a simple number...being 3456.
I have also seen the equation with an additional step...multiplying by a coefficient of efficiency. Most carbs/setups being only 85% efficient so you would then multiply the 615.xx cfm by .85 to give you a closer number.
Racing setups or blown applications might raise the coefficient to 1.1. 615.xx cfm x 1.1.
But it won't REALLY matter. just leave that step out and you're in the ballpark. It's not like someone actually makes a carb that fits your equation number EXACTLY...I mean can you go out and buy a 522.xx cfm or 676.xx carb?
