Our 6.4L 392 VVT HEMI Performance HI-RAM MAX EFFORT NA Camshaft is designed for the 6.4 Hemi Owner who wants max power on a stock bottom end 392!
This camshaft with Ported Heads, 105MM Throttle Body, Holley 105MM HI-Ram Intake Manifold, made 126HP Over stock on our Superflow Powermark Engine Dyno!
After years of Research and Development we are proud to release our all-new MMX HI-RAM 392 Max Effort Camshaft! This camshaft will squeeze as much power out of a stock piston 392 as possible! This camshaft is specifically made for short runner intake manifolds like the Holley Hi-Ram, Ritter Intake, Drag Pack Intake, Holley Single Plane, and Prefix Intake Manifolds. This new grind is made to take advantage and make max power out of the shorter runner length these manifolds provide. This camshaft works best with a 92-108MM Hellcat Style Throttle Body, Long Tube Headers, Holley Hi-Ram Intake Manifold, and CNC Ported Cylinder Heads. Our New Grind Makes Peak Power at 7000RPM and will stay flat until a few hundred RPM past that.
This camshaft WILL also work well with the OEM intake manifold! We have seen 531WHP here on our in house chassis dyno!
Due to the VERY tight confines of the stock bottom end 392, it is not recommended to mill heads or use a thinner than stock head gasket with this camshaft on the stock bottom end.
