Chevrolet Performance L8P 6.6L 400 C.I.D Engine Assemblies

By combining the large-displacement and heavy-duty elements of the L8T 6.6L engine and a unique camshaft based off the Corvette Stingray's high-revving LT2 V-8, Chevrolet Performance engineers have created the all-new L8P 400 c.i.d. Performance crate engine. Rated at 523 hp and 543 lbs.-ft. of torque, it offers your project a unique and naturally aspirated combination of big-displacement torque and high-rpm horsepower. The L8T 6.6L foundation is the same high-strength, big-displacement engine found in the Silverado HD from 2020 to present day, featuring a forged steel crankshaft and high-strength components. Additional features such as oil-spray cooling for the pistons and a cast iron, long-skirt cylinder block with 6-bolt, cross-bolted main caps contribute to the engine's strength and durability. The new L8P builds on that with a unique, upgraded valvetrain featuring performance-oriented valves and springs, along with a unique camshaft that is based off the Corvette Stingray's LT2 engine. It has a non-active fuel management profile and more duration than the L8t's camshaft. It's the best of both engines: the largest displacement in the LT family and the power-building attributes of the Corvette camshaft. Put it to work in your project. Fast Facts: * Displacement: 400 cu. in. (6.6L) * Bore x Stroke: 4.06 in. x 3.86 in. * Crankshaft: Forged steel * Pistons: Hypereutectic aluminum * Compression ratio: 10.8:1 * Cylinder heads: Rectangular port D/I with 59.02cc chambers * Camshaft type: Billet steel hydraulic roller * Camshaft duration: 218 degree intake/231 degree exhaust at .050 in. * Fuel delivery: Direct injection with high-pressure pump * Horsepower: 523 at 5,800 rpm * Torque (lbs.-ft.): 543 at 4,800 rpm * Engine type: Gen V small block V-8 direct injection spark ignition * Block: Cast iron with 6-bolt no Dula main bearing caps * Connecting rods: Forged powder-metal * Valve lift (in.): 0.549 intake / 0.549 exhaust * Rocker arms: Investment cast roller trunnion * Rocker arm ratio: 1.8:1 * Intake manifold: Composite * Throttle body: 87mm diameter (single-bore) * Fuel delivery: High-pressure direct injection (2,175 psi / 150 bar) * Recommended fuel: Premium pump * Ignition system: Coil-on-plug * Maximum recommended RPM: 6,000 rpm * Reluctor wheel: 58X * Balanced: Internal * Note: Use with the new engine control kit, P/N 19435524, which includes a programmed controller, wire harness, pedal, oxygen sensors and mounts, MAD, fuel line pressure sensor and fuel pump power module.
