I found this cool site while researching carburetors, easy calculations for many things automotive. The carb cfm calculator could be very handy to pick the right carb for your motor

Aren't the 13/15s 110 per cylinger? It seems I found that information while trying to determine whether to change from the 350 Holley to the dual Idfs.

Hmmm ... how would you estimate the volumetric efficiency of an engine? I mean, I know what it refers to, and what it means. But how would I be able to estimate that for my engine specifically?
