More Power from Chevrolet Performance's Largest Displacement LT Engine!
We’ve optimized every cubic inch of our largest-displacement LT engine with the unique L8P performance crate engine. With 523 horsepower and 543 lb.-ft. of torque, this package combines the displacement and heavy-duty strength of our production-based L8T 6.6L engine plus a unique LT2-based camshaft.
It’s all rooted in the tough foundation of the L8T, with a forged steel crankshaft, high-strength parts, high-flow heads and composite intake manifold. We then add a more performance-oriented valvetrain, including valves, springs, and a unique non-AFM (Active Fuel Management) LT2-based camshaft. The net result is an increase of 122 horsepower and 79 lb.-ft. of torque over the production 6.6L engine.
Our L8P crate engine package comes complete from the throttle body to the oil pan, including the PCV tube, evap tube, oil dipstick, oil fill tube and cap. It does not include the controller, harness, oxygen sensors or a Front-End Accessory Drive system. See Installation Notes below for recommendations.
