LB7, LLY What does it all mean?


I'm in the research phase of purchasing a used Duramax truck. I understand that LB7 is an engine designation but does it refer to anything specific about the engine? I think I want a 2000 - 2004 Duramax, I'm mostly picking this range because it puts them more in my price range. I have a Dodge Ram 2500 with a Hemi right now and kick myself for not getting the diesel. As my username implies, I want to start making my own BioDiesel. I'm looking for a Duramax, because based on people I've talked with and post I've read, it seems to get the best mileage out of the big three. I'm looking for a crew cab, 4X4, and I'd prefer a long bed (I could fit my motorcycle in there and still close the tailgate). I live in South Florida and there doesn't seem to be lot of used ones with all of those things I want. Texas seems to have quite a few, and they run between $19,000 to $24,000 for one under 100,000 miles. Any ideas or suggestions are welcome.

The engine designations have to do w/the generations. Each designation they changed, some things, mechanical, upped the horse etc. I think a crew cab long bed will be hard to find. I had a problem when buying my 07 finding an ext long bed w/the options I wanted, ended up getting a new one. Compared to what htey were getting for used 30,900 for a truck w/30,000 miles or spend 38 on a brand new one, I got a new one.
