The Sonoramic Commando Intake?

Well, to put this in far more general terms, a cross-ram, a tunnel ram, and a "long tube" ram all "are the same thing" they are just tuned at different RPM / torque levels. A tunnel ram, with variations, is basically simply a vertical crossram with a lot more plenum, and with the plenum far more interconnected than "some" crossrams. Hell, there's Great Big Books written on this, and it turn out, not all of them were right, LOL.

Just look at the mods you were supposed to do to an Edelbrock SBM crossram to make the darn thing run.
