I gotta question....Magnum intake parts...

Rumble those parts must be used to install a M1 on a Magnum engine. Don't look like anything we'd ever use on a LA.

I looked in the mopar performance catalog and couldn't find out anyting on the M1. They list it but don't give a rpm range.

I see what your saying about the rpm range on Summit. Summit's site probably screwed up the rpm rating. Lately I've caught allot of errors on Summit. In the past I have usually seen the single plane rated from 2000-6000 and the dual plane from idle to 5500.
