the vin numberll tell you 8th digit or the sticker under the hood if it says 365 horse its the lbz. the blocks are a bit different, the lbz's dont seem to have wiring harness, overheating problems like the lly'd

1996 Gmc k2500 4x4 6.5 turbo diesel, with mods Blew the head gasket, put all new heads, valves, injecotrs gaskets etc on the truck only to get it together and find out it had no oil pressure, and sounded horrible (pry a spun bearing). SOLD

The 06 LLY and LBZ are the same truck, different tuning.

The earlier LLY have a hot air intake, different PCM, only 1 IAT sensor (LBZ has an IAT2), and a few other things.

and the compression is less plus I think they switched to a 32? bit processor for the computer. Only the lbz's have the six speed.
