Why Choose the Chevy 6.0 LQ9 Vortec Engine

GM rated the LQ9 at about 345 horsepower, making it the most powerful 6.0L Vortec of its era. Flat-top pistons raise compression over the LQ4, and the cast-iron block is famous for strength under boost. Builders often pick the Chevy 6.0 LQ9 Vortec engine as the base for turbo projects because it can take serious power with relatively few internal upgrades.

Before You Buy

• Choose an oil pan and accessories for your chassis.

Installation Tips

Replace the rear main seal, water pump and thermostat, and prime the oil system. Have the computer tuned for your transmission, gearing and any boost.
