Whos running a 5.9L Magnum ?
I'm running one and like it a lot.
I left the shortblock as it was in the Durango.
I put on a Kevko pan, custom hydraulic roller cam, RPM Air Gap, Quickfuel 750 DP, 1-5/8 Hooker Comps through 2.5" X-pipe. Stock rocker gear, Iron Ram heads.
I converted it to LA style serpentine setup and had the Iron Rams drilled for LA intakes.
Times in sig for my full weight bench seat car.
