I should clarify that I am not trying to make a hot rod. I am putting in 3.40 gears and plan to drive it around town or maybe to meets at 50-55 tops. At 1:1 I should be at 2000-2500 rpms. The carburetor that I have is the Zenith 11658. It has a main Venturi of 34mm. Jon mentioned that it should be around 220cfm. Mine has an 1 11/16" throttle bore. 228BV12.
I found an equation that Jerry (hotrodlincoln) posted in an old comment where ((CID/2)*RPM)/1728. Based on this equation and that you can assume 90% Volumetric efficiency I should be about to run about 3250RPM AT 220CFM with the one carb.
Only above 3250RPM would I have any issues, am I thinking this through correctly?
