out of the stock 6.0L LQ9, from the factory they are rated at 340hp/385tq, and some belive this to be a conservitive rating (my self included, since i have one in my truck) these bottom end and heads on these trucks are capable of every bit of 500+hp/tq the only modification that needs to be made really is the intake system, valvetrain, and some good headers. these motors are very saught after due to their strenght and heads.

a carb kit like this one (minus the carb)



these parts would have the 6.0L pushing 435-465hp/450tq
