The Chevrolet Performance LS3 6.2L Crate Engine (SKU 19540155) offers proven power and durability, making it a top choice for enthusiasts and builders. Based on the C6 Corvette engine family, this high-revving engine is constructed with an all-aluminum LS3 block, a 3.622-inch stroke nodular iron crankshaft, and hyper-eutectic aluminum pistons. It features a high-lift hydraulic roller camshaft and high-flowing, rectangular port L92 design aluminum cylinder heads, contributing to its impressive output of 430 horsepower at 5900 RPM and 425 ft-lbs of torque at 4600 RPM. The engine includes the EFI intake manifold assembly with injectors and throttle body, water pump, harmonic balancer, and oil pan. A 58X reluctor wheel is also integrated. For optimal installation and operation, the use of the factory-engineered Chevrolet Performance LS3 Crate Engine Controller Kit (P/N 19354328) is recommended. Note that exhaust manifolds and the flexplate are not included in this crate engine assembly. The Chevy SS oil pan is included but may not suit all applications; a vehicle-specific oil pan or Chevrolet Performance's Muscle Car Oil Pan Kit (P/N 19212593) may be required for older vehicles. This engine is intended for competition use only, pre-1976 street vehicles, or any off-road vehicle. It is not intended for marine applications. Consult the installation guide and warranty registration card for further details.
