I have a 1970 Chevy Nova 350 small block bored out with a 383 stroker. I need to put a new carb on, and would like some opinions as to what size carb I should put on. I am looking at edelbrock. I refuse to put a holley on, I have had nothing but issues with those carbs. Any information you guys can give to me will be greatly appreciated. Also, does anyone have any links to websites I can use to help determine the proper carb? Thanks guys
A good baseline formula is (displacement x rpm)/3,456, however this formula assumes 100% volumetric efficiency (VE). A strong street & strip motor will usually be somewhere around 85% VE, A race motor may come close to 100%. Take the results from the formula x your approximate VE. For example, if you plan to turn your 383 6,000 r.pm. max, and it's a street and strip motor, 383 x 6000/3456 = 664.73 x .85 = 556.19 cfm air flow, so a 600 should work well. Most people vastly overestimate the size of the carburetor that they actually need which makes it almost impossible to get the air/fuel ratio correct. The maximum rpm is the biggest determining factor in the equation and since most street motors run flat tappet hydraulic cams which are limited to under 6,500 rpm even fairly large cubic inch street engines don't really need all that much cfm.
