Yes, it was the last model year before the ACERT engines came out. they call it a "bridge" motor because CAT did not come up with the EPA emissions motors in time, so they made the MBN engines till they finished the ACERT design. The standard MBN motor is basically the same as the 6NZ just with a different cam and ECM program. Luckily, you can swap in a 6NZ computer or just have the ECM reflashed over to the prior motor to get the same effects. I have been told by a few people that this motor will run well into the million mile range with proper care and maintance, it just gets bad MPG (not as bad as the ACERT) and is a dog. Luckily for me, this truck already has a 6NZ "Hot" tune done and Pittsburgh Power free-flow mufflers and a few other things. I just got back from vacation, but I'm anxious to get it on the road and see how she does. With the tune, it idles so smooth and the throttle response is amazing.
And as for the LUG tires, I had no say as they were already on the truck and were brand new, along with the steers. if I can get thru till next spring then i will be very happy and then going with some M726EL or TY577's
