In February, the specs on Ford's 6.7-liter Power Stroke turbo-diesel V8 were announced: 390 horsepower and 735 pound-feet of torque. A month later, General Motors laid out the specs on its 6.6-liter Duramax turbo-diesel: 397 hp and 765 lb-ft. According to PickupTrucks.com, the Duramax could be shoved to the corner again later this year, when a high-output Super Duty blows out the footlights with 400 hp and 800 – or more – lb-ft of twisting gumption.
According to the unknown source within the Blue Oval, Ford's new 6R140 TorqShift six-speed transmission has strong enough guts that Ford can open up the taps on that engine a bit. And give GM something to think about. If this absurdly powerful dream does come true, the behemoth motor will be seen in the second wave of 2011 Super Duty pickups that begin production in a few months. No word on whether early adopters of the 6.7-liter will get a free upgrade.
