Has anyone seen the specs on the new duramax diesels? Chevy's website shows that for engines produced after septemeber 2005, the duramax mated to the allison 6-speed auto produces: 360hp @ 3000rpm, and 650 ft. lbs @ 1600 rpm! Thats insane. 650 ft lbs at 1600 rpm!!!! Now, if only chevy would put an sfa under there.
