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.

Quicksilver's long block assemblies are all-new (not rebuilt, remanufactured, or reconditioned) marine engines and feature improved components, technology, and built-in durability designed to withstand years of marine duty--one of the most abusive and demanding environments for any engine. The foundation of every Quicksilver long block engine is a new iron block cast to Quicksilver's specifications and designed expressly for marine duty. Thicker castings ensure quieter operation and better durability in saltwater when compared to a standard automotive block. They feature Black-X composite valves that contribute to a 42 percent reduction in valve wear compared to traditional stainless steel valves with hardened seats, while smooth-flowing cylinder heads deliver added performance. Quicksilver Value Series long blocks are cost-effective solutions when replacing an engine with a reliable fuel system and dress components that can be reused, typically when the original engine block has suffered freeze damage. Select the long block needed for your build.

The hot new small block V8 in the GM lineup is the hyper-aggressive LS3 6.2L 376 c.i.d. 495 hp engine assembly from Chevrolet Performance. It offers a high-revving 376 c.i.d. combination that represents generations of small block V8 development and engineering. Not only is the LS3 an amazing engine in its stock configuration, but with those high-flowing rectangular port cylinder heads, the LS3 is loaded with potential. To tap into this, the engineers at GM Performance Parts offer you the LS376/480—an LS3 with an upgraded camshaft that boosts power by a whopping 50 hp! The LS376/480 comes with the same great features as the LS3 crate engine. The bottom-end includes a 6-bolt aluminum block, nodular crank, high performance rods, and 10.7:1 pistons. The heads are high-flowing rectangular-port L92 units that have been upgraded with high-revving, hollow-stem valves. The same EFI intake manifold feeds the hungry engine, while 1.7:1 roller rockers work with the upgraded camshaft. The GM Performance Parts engineers picked the LS Hot Cam (P/N 88958733) to take the LS3 to the next level. This cam specs out with .525 in. intake and exhaust valve lift. Duration (at .050 in.) is 219 degrees intake and 228 degrees exhaust, which allows for a dramatic increase in power. The engine will idle and cruise just like an LS3, but the power increase is there whenever you need it. A 14 in. automatic flexplate is included. Specifications: * Engine type: LS Series Gen IV small block V8 * 495 hp at 6,200 rpm, 473 lbs.-ft. torque at 5,000 rpm * Displacement: 376 cubic inch (6.2L) * Bore x Stroke (in.): 4.06 x 3.62 (103.25 x 92mm) * Block: Cast-aluminum with 6-bolt, cross-bolted main caps * Crankshaft: Nodular iron * Connecting rods: Powdered metal * Pistons: Hypereutectic aluminum * Camshaft type: Hydraulic roller * Valve lift: .525 in. intake / .525 in. exhaust * Camshaft duration (at .050 in): 219 degrees intake / 228 degrees exhaust * Cylinder heads: Aluminum L92 style port; as cast with 68cc chambers * Valve size: 2.165 int / 1.59 exhaust * Compression ratio: 10.7:1 * Rocker arms: Investment-cast, roller trunnion * Rocker arm ratio: 1.7:1 * Recommended fuel: 92 octane * Maximum recommended RPM: 6600 * Reluctor wheel: 58X * Balanced: Internal
