The Sonoramic Commando Intake?

They were Chrysler OEM only. Tuned for low RPM torque. The "shorter length ones were for a higher RPM. They were not on newer cars, mid 60's, not on "A" bodies that I know of. I always thought they were very cool, just too expensive to justify for myself. I'm pretty sure they will bolt to all but the Max Wedge or Hemi heads. They had different exhaust manifolds also. By the time the Hemi was deigned they would be a serious power loss as the Hemi was built for high RPM.
