YEp your dad's truck is an LBZ. IN the new body style is when the LMM came out. The LBZ is a stong motor. IT's got about 50 more hp than the LLY. They do run pretty good.

LBZ is a more refined version of the Duramax. More power and a stronger block.

That is true. But that is where the similarity ends. The 06 LLY and 06 LBZ, are identical in every way, except for tuning, which is a mute point as soon as you hook up a tune.
