Um, the GXP and the 300C have the same number of cylinders.
I forgot this little detail. This version of the Hemi had MDS (multiple displacement system). It'* cam followers are hydraulic cylinders. The engine can open valves on individual followers and therby disabling the valve associated with it during low load conditions. That saves fuel.
So, yeah, it has some more technology in that department.
