Show original supplier description
The Chevrolet Performance LS376/525 is a factory-engineered long block crate engine that merges the robust LS3 6.2L production engine with the high-rpm racing-proven ASA camshaft. This combination results in a powerful street-capable engine delivering 525 horsepower at 6,300 rpm and 489 lb.-ft. of torque at 4,400 rpm, making it a strong contender for performance applications. Built on a cast aluminum block with 6-bolt, cross-bolted main caps, this engine features a nodular iron crankshaft, powdered metal steel connecting rods, and hypereutectic aluminum pistons. The cylinder heads are aluminum L92, and it is equipped with a steel hydraulic roller tappet camshaft featuring 0.525" lift and 226°/236° duration at 0.050". It requires 92 octane fuel for optimal performance. As delivered, the LS376/525 includes essential components such as the intake manifold with pre-installed injectors, fuel rail, and throttle body, along with the water pump and ignition system. However, front-end accessories and an engine controller kit must be obtained separately. Some installations for older vehicles may necessitate an oil pan change. Note that shipping for this item may be excluded from free shipping promotions and requires truck freight.
