C.F.M. = Capable Force Measurement. / Cubic Feet Per Minute ~ So...
Too Big: No Harm ( Unless Jets are too Big.) FLOOD - OUT ENGINE. Low Vacuum.
Too Small: Like a GOVENER, Low R.P.M.s MAX. " Lots of Manifold Vacuum!
The reason it is called a 350... 350 C.F.M. Used in the Center of Tri Power,
With 500's On the Out Sides.
