In my search for a new to me truck, I was wondering if mechanically the LBZ is more desirable than the LLY. I know the LBZ has a higher torque and Hp rating, but I am finding more LLY's from 05 than I am LBZ's from 06. Would an LLY with some mods do as well as an LBZ? If I have a choice between a lower mileage LLY and a higher mileage LBZ that costs a few thousand more, is it worth it to get the LBZ?
