:rockYou can still buy an F650 with a CR Cummins and an Allison... however they are the industrial versions and you can't exactly crank big power out of them without converting all of the electronics to a light duty style setup. This forum is for those of us who love our Ford trucks, and the Powerstroke leaves a lot to be desired. Therefore we transplant the Cummins motors into our Fords and drive the baddest trucks on the road.
