2011 Ford Super Duty: 2011 Ford Super Duty Engine Mule Shows Off Replacement To Stroking?
Apparently, Ford is ending the contract with international for making the Navistar engines (due to cost and warranty issues), is coming out with a new 6.7l diesel with a new transmission to go with it. The engine is currently in an 2008 body with a bigger hood. Has any one found out more information about this change that Ford is doing????
