Thanks E.Furgal, for mentioning the difference with vacuum secondaries. I see this discussion a lot on hot rod sites, but they all seem to focus just on the mechanical secondaries. I have always thought that vacuum secondaries gives you the responsiveness of a smaller cfm carb at the midrange, but still gives the full cfm power at the upper end.
