Holley Ford 7.3L Godzilla High-Mount Accessory Drive Complete Kits

Holley's Ford 7.3L Godzilla high-mount accessory drive complete kits with their patent-pending technology, integrates timing cover, oil pump, oil pan, water pump, alternator, and the option for A/C and/or P/S, all in one streamlined system. Plus, they are compatible with both factory crank pulleys and aftermarket damper/pulleys. Positioning an engine swap correctly is crucial, ensuring it aligns with the vehicle's original engine's crankshaft centerline. Holley's innovative solution achieves just that, allowing proper engine placement while providing clearance for a stock Fox Body hood (when used with a low-profile intake). Our system replaces Ford's sump-mounted oil pump with a high-capacity gerotor pump positioned behind the timing cover, gaining crucial crossmember and ground clearance. To ensure reliability, they incorporated a proven pump design utilizing Melling sourced components that mimics the factory pressure level. Unlike most pumps that require removing the oil pan to change the pressure spring, Holley introduced a first-of-its-kind external access port, allowing hassle-free spring switching. Moreover, their cast aluminum oil pan features a performance-minded windage tray and baffle, guaranteeing proper oil pickup during high-G maneuvers. For extreme situations, such as drag racing, upgrade to the optional race baffle to always ensure proper oil delivery. These accessory drive systems offer flexible configuration options to meet various needs, making Holley's Godzilla high-mount accessory drive kits the ultimate solutions for engine swaps, offering unparalleled functionality, adaptability, and ease of installation. Choose from natural as-cast aluminum or black finish.

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.
