No, in 06 they had both the LLY and LBZ. The LLY in 06 was basically just a detuned LBZ.

And there was no 08 classic. By 08 they were all LMM NBS, it was in 07 they offered either the Classic OBS LBZ or NBS LMM.

Sounds like a good deal

Back to the earlier topic, as much as I love Cummins, if youre lookin for immediate power without having to do a lot of mods, the Dmax is the way to go. I'm actually plannin to get an LBZ/LMM after I graduate in about a year and a half.

I have seen LBZ/LMM's make nearly 600hp and run mid 12's in the quarter with nothing but a lift pump, tranny upgrades, and a strong EFI Live tune.

 

How can i tell if its an LLY or an LBZ? And for my previous question, anything i should look for on the truck?

 

Look at the eighth digit in the vin, if its 2 its an LLY and if its D its an LBZ.

 

2 words Head studs. then forgeet about it

 

What kind of longevity are people getting out of the Duramax? The Cummins has a very good reputation for lasting. The 1,000,000 mile Cummins club has quite a few entries, while Ford doesn't have many entries - and I haven't heard of any Duramaxes with high miles on them before an overhaul occurred. MTBO on GM was 200k, Ford was 250K and Dodge/Cummins was 350K. If you are going to keep the vehicle for a long time - or you put a lot of miles on, the Cummins is the obvious choice. The Duramax competes on power, but the advantages of fewer moving parts, heavier duty parts and more bearings to spread the load really help out when it comes to longevity. If you only keep the vehicle for 100k miles, it probably doesn't matter to you. If you plan on keeping it longer - it may affect your decision.

 

I personally think no matter which diesel engine you pick, the truck is going to start falling apart long before the engine goes. The engine may last 250k, 500k, 750k or even a million miles, but you're going to have to do ALOT to keep the rest of the truck road worthy with those kind of miles, and that costs $$$$$$$.

The highest mileage Cummins I have ever seen is about 400k-500k miles, there are higher mileage ones out there, but they are rare. Heck even the donor truck I bought had 400k, and the engine had to be rebuilt at 350k miles. And before you start to say the truck was mistreated, the pump, intake, and even the exhaust were bone stock.

But in the end, yes, I do believe a Cummins engine will generally last longer than a Dmax or PowerStroke.

 

Well went to dealer friday to look at the Duramax, 3 words. BEAT TO HELL! **** this truck was in bad shape, but in the end for the same price, picked out a clean 2007 Ram 2500 5.9L 83K on it, get to pick it up friday after some insurance **** falls into place, ill post some pics when i get them. Asfar as i know, the truck alrdy has an exhaust, its ******* loud as hell, sounds sexy might i add, but yea, when i pick it up friday i will post some pics for you all. thank you guys for all your help, it really did help in the end.
