Yea dodge does have the lead but 40 extra ft-lb of tourque is not that much. Yea maybe you could tell hauling up a hill but other than that no. Navistar will up grade the 6.0L soon and it will have more hp abd tourque than both of them. If you wanna top the cummins and you own a 6.0L now and want around the same tourque and more hp go buy a banks monster exhsaut. It will increase you hp to 342hp and increase your tourque to 585.
