6.7?
You can just do a search here on DTR. There are several threads discussing the 6.7. Basically, it is a bored out and longer stroked 5.9 that has EGR and particulate traps and other stuff for emissions control thanks to new diesel regulations going into effect on Jan. 1st. Also, DC is discontinuing the 48RE auto tranny and replacing it with a new 6 speed auto.
