The strongest Duramax ever is the 2011 Duramax that will be coming out in Summer of 2010. It produces 397 horsepower and 765 pound feet of torque. But the truck that this 6.6L sits in still can't tow or haul as much as Ford's new 6.7L Powerstroke which produces less power, at 390 horsepower and 735 pound feet of torque.
