Pulled the grade myself this weekend. I had the 7.3 humming, 2800 rpms, 15 psi on boost, and the tranny spiked to 180. Not too bad in my humble opinion, considering truck trailer and all we were at just over 19,000 lbs.
Yeah, the 6.0L pulls like a raped ape and will do it all day long! The factory 5 spd automatic trans is almost bullet proof and prolly the best one Ford has made in years.
