Chevrolet Performance Stock Replacement Non-DOD Camshafts

If you're looking for a cost-effective camshaft solution to delete that pesky DOD—Chevrolet Performance stock replacement non-DOD camshafts are the answer. They're designed to work with OEM valve springs/pushrods in the DOD-equipped Gen 4 trucks. These OEM camshafts are standard equipment on non-DOD 5.3L trucks. Since they come as a single-bolt style, new timing gear won't be necessary. Just swap cams and additional DOD delete parts (sold separately) and you're ready to roll! A fairly stock truck shouldn't require dyno tuning; however, the DOD system must be disabled in ECU for proper functionality. It is advised to consult with your tuner for more information. Order the model recommended for your year/make and engine application. Additional features include: * Hydraulic roller tappet cam * Single-bolt camshaft gear attachment * Computer-controlled compatible * This is the camshaft only (other components sold separately)

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.

Chevrolet Performance LS9 CNC-Ported Cylinder Heads

Chevrolet Performance LS9 CNC-ported cylinder heads represent a new benchmark in factory engineering high performance, blending the strength and durability of the production LS9 cylinder head castings with the airflow enhancements of precision CNC porting. The result is about 10 percent more efficiency than the production casting, while delivering the greater strength built into the LS9--Rotocast from super-strong A356T6 aluminum alloy. With the Rotocasting method, the mold rotates to more evenly distribute the molten alloy, creating a denser casting that virtually eliminates porosity. And compared to the similar LS3 heads, Chevrolet Performance LS9 CNC-ported cylinder heads feature reinforced webbing and a thicker deck for greater rigidity and minimal distortion. The A356T6 alloy also manages the higher heat of a forced engine more effectively. The heads come fully assembled with production, lightweight titanium intake valves, sodium-filled exhaust valves, and strong beehive-type valve springs that can handle up to .570 in. lift and can be installed on any LS engine with at least a 4.000 in. bore using standard 11mm head bolts.

Chevrolet Performance Bowtie Aluminum Cylinder Heads

Chevrolet Performance Bowtie aluminum cylinder heads offer an ideal combination of street drivability and drag-strip performance. These aluminum cylinder heads provide a broad power range with ample low-end torque, along with excellent throttle response, good mid-range torque and enough top-end power to beat your competitors to the finish line. Designed for high performance applications, the Bowtie Street cylinder heads are manufactured to precise machining tolerances, with thick deck surfaces and high-velocity airflow passages. They are available in either rectangular or oval intake port configurations. The rectangular intake ports are larger in volume and have been designed to enhance high-rpm horsepower, which makes them best for vehicles that see frequent drag-strip action. Cylinder heads with oval intake ports are smaller in volume and designed for greater low-rpm torque, therefore they're best for street applications, where lots of bottom end, off-the-line power is desired. Bowtie Street Cylinder Head Technical Notes: * Made from 356-T6 aluminum * Available in rectangular or oval-port designs * Will work on Mark IV and Gen V, VI blocks * 9/16 in. thick decks * As-cast intake and exhaust ports * No heat risers * 1.55 in. valve spring seat diameter * Heli-coiled 7/16 in. screw-in rocker stud holes * Designed for use with 3/8 in. pushrods * Use intake gasket P/N 12366985 and bolt kit P/N 12367959 * Use head gasket P/N 12363414 for bores to 4.370 in. and P/N 12363413 for bores 4.470 in. to 4.540 in.

Chevrolet Performance Valve Stem Seals

These Chevrolet Performance valve stem seals control the lubrication of the valve stem as it slides into the valve guide. Too little oil contributes to stem and guide wear, and too much oil increases oil consumption and can cause a buildup of carbon. This leads to valve seat damage and early valve failure, as well as reduced engine performance and emission failures. These Chevrolet Performance valve stem seals ensure dependable performance and superior service life.
