By the time 06, 07 rolled around, the 6.0 was pretty well sorted out. I've seen them run back to back with the 7.3 and the 6.0 is a much more refined engine. 4 valve heads and it sounds like a beast with a good exhaust next to the oddly fluttering 7.3.

Plus, a plug in box will provide upwards of 400 HP.

Don't get me wrong, I enjoy my 7.3 but it's old tech compared to the 6.0. Also keep in mind that the 6.0 wasn't just made for the F-series. It's well utilized, working hard every day as the VT365 in the 4000 series International trucks.

Oh, and one last thing: The 6.0 has the excellent torque shift automatic while the 7.3 has the troublesome A4OD or whatever it is. Mine is a manual 6 speed.
