The 7.3 is a rock solid beast that will run forever. Had an excursion with 7.3 and it was a beast. Stock it wasn't that powerful, but it didn't have a problem towing what I pulled.

Pretty sure my 6.0 was a 05'. Never had one single problem with it. But my partners had them same truck and they were always in the shop. Around 75k I put a tune in it and it was evil. That truck ran like a raped ape. Finally traded it out around 2008 and got a 6.4

If you get a solid 6.0 they're amazing. Problem is I think good ones are few and far in between. I've heard 7.3's are hard to find.

My 6.4 was questionable. It had a egr clean cycle that was just embarrassing. The truck would puke white smoke for minutes at random times. If not for that it would have been a great truck.
