Multi-displacement hemi for JK ?

[honoredson]

Is the fuel-saving multi-displacement, variable-valve-timing hemi available for JK conversions ? This engine is said to get great fuel milage in the new Dodge trucks, and if this is true, then it should get even better fuel milage in the lighter, smaller JK Rubicon.

I would guess the milage would be similar, or maybe even worse. A rubicon isn't as aerodynamic as the Dodge trucks, and also once you add on bumpers, skids, tires, etc... they are both similar weights since a quad cab 1500 is about 5100 lbs, and Dave mentioned his Rubicon was about 5500 lbs if I recall correctly.
