01-04 LB7 have injector issues, but are still a great engine.
04-06 LLY Have had overheating issues, but there are some great fixes out there now!
06-07.5 LBZ Strong motor with the six speed auto.
All of the auto's will at some point need modded if you add more power to the engine in the form of tuners. The LB7 and LLY are both 5spd auto's but can be modded to a 6spd with a kit from Suncoast Converters.
