The Sonoramic Commando Intake?

First off, the longram intakes do Not fit on Hemi's.
They were only available on some high-end Chryslers, Dodge and Plymouths. Not on Imperials.
That's not to say someone could have swapped them into an Imperial or any other cars that they would fit in ofcourse.

I have installed a set of longrams in my '60 NewYorker.
It originally came with a 4bbl-413, but I replaced it with a 496" stroker with longram intakes.
