The Sonoramic Commando Intake?

So, they were merely for low end torque and low RPM's, that, I did not know.....

I knew that the Cross-Ram used on the Hemi back then was for high RPM's, why was the Sonoramic Commando Intake low RPM tho? Or well rated as such, did it restrict fuel/air flow or what?

different exhaust manifolds, why?

These damned things look cool as hell but are a complicated SOB just to understand, I can see why the guys trying to "tune" in the whole set up complain!
