Your friend is really wrong in his feelings. It'd be like us saying there is no difference between the 1997 F150 and the 2007 F150. Even though the 5.4L engine is still mated to a 4-speed auto, we all know there is a TON of differences between the powertrains used by Ford over the last decade.

Yup, GM has the same displacement engines as they did in 1999, but they are by no means the same engines. Heck, the 2007 engines (Gen IV) are even different from the 2006 engines (Gen III)!

Still, despite all the hype, I've not seen any of the new trucks on the roads either. I hear they are selling like crazy, I just don't know where!
