Try this, There is a formula that will get you very close to the proper cfm for your engine. The formula goes like this: cubic displacement divided by 2 (ex: 351=175.5) maximum rpm divided by 1728 (ex: 6000 rpm=3.47) multiply those two figuires (ex: 175.5 x 3.47=608.98 cfm) Hold on we are not done. You now have to factor in volumetric efficiency. A Nascar race engine runs at 85%-90% volumetric efficiency. A normal street car wil be 75-80%, depending on what you have done with your heads and exhaust. Ex: 608.98 x 75%=456.74cfm I have noticed a lot of interest in Carb sizing and jetting info.Firstly the biggest mistake we make is to put too big a carb on the motor and then try to adjust it to run right.Hers a formula for working out the correct size carb.
