I believe they redesigned the injectors and and fixed the overheating issue.

heads, block, crank, pistons, rods, injectors, ecm are all different. the lbz has no FICM on it either.

06 LLY is the same as the LBZ just different tuning from what I understand. All other years have different hard parts like said in the post before me.

FICM=Fuel Injector Control Module

06 LLY/06 LBZ is essentially the same engine, just different tuning. 04.5-05 LLY engines are different from 06LLY/LBZ and 06-07 LBZ. Make sense?

The major difference is the injection system.

the 2006 LLY is a DE-TUNED LBZ, that is the ONLY difference, you can easily remedy that problem:tu:

the 2005 LLY is entirely different than the 2006 LLY, the 2006 lly is built exactly the same as the LBZ
