a 2006 LLY is actually a detuned LBZ. whether or not any of the metal pieces are interchangeable I cannot say, but the electronics are different
as are a lot of the overall design, such as compression ratio, different pistons, etc.
The 04.5/05 LLY has a 16 bit computer, the 06 LLY has the LBZ's 32 bit computer. IIRC the injectors run on different voltages.
this is why there is why the 06 LLY is included in the LBZ forum right above the LLY forum here on DP
just for the record DRCook = David R Cook - not Dr Cook, but thanks for the compliment
