What truck do I have?

[2007 3500 CC DRW]

I love this forum and my dually. I bought my truck about 1 month ago and joined this forum shortly after. I have a question. I see everyone posting LBZ, LMM, and so on. My truck is a 2007 Crewcab Dually 2wd, I have he six speed allison tranny and the Classic body style. If someone could chime in and let me know what all of these accrunims mean that would be great. Also what are the possible short coming or weak points on my truck. Sorry for the long post any help would really be great.

look at the 8th letter in the vin.

The lbz to my knowledge really does not have a week point. The lb7, has injector issues, the lly has over heating issues and the LMM really the only thing that ppl dont like is the DFP exhaust filter which will not get good fuel mileage with it on.

LBZ are the best of the best.

The 8th letter in my VIN is a "D", also LBZ motor what does that mean, LMM, LB7 what do all of the abbreviations mean?

Different year trucks with different motors

So the LB7 is what I have? And this motor does not have the injector issues I have read about on the forum?
