Re: how many cfm for two carb flathead??
hello frank... the factory book says that the 94 is rated at 162 cfm, so two would be 324 cfms. At 255 ci mercury engine at less than 4500 rpm these two carbs are over the top in requirements! but everybody still does it! So I'm thinking of reducing the internal ventrie
of the 94s to make them more compatible with MY engine size ??
