It might be good to know that a tunnel ram is not as cfm dependant as a dual quad intake manifold or dual plane intake.
David Vizard
"First, the port runners are a straight shot to the cylinder head ports, so the manifold is more flow efficient. Second, the carb barrels are directly over the manifold’s port runners so fuel distribution problems are minimized. Third, most wet flow problems arise due to a runner’s change of direction but because a tunnel ram’s runners are almost straight it has fewer issues with wet fuel flow. Finally, the pressure-wave tuning brought about by the interaction of the plenum and the port runners is far better than with any single-carb intake. All this adds up to a better result for a given amount of carb CFM."
