I see your point. Engine manifold vacuum will determine the actual
flow...correct? And a carburetor will have a stronger signal. Ultimate flow
potential would be a different story...right. The 446 cfm number I gave out
is a "book" number based on flow bench data. Never having had a flow bench
to play with I can't substantiate it.
