A Contemporary Classic

LS long-blocks from Chevrolet Performance offer the core capabilities of complete crate engines at a lower cost, allowing builders to finish the assembly their way. The LS3 long block is delivered without the intake manifold, coil packs, water pump, exhaust manifolds or other accessories

Destined to go down in history as one of Chevrolet’s most versatile performance engines, the 430-hp LS3 6.2L offers a fantastic combination of modern technology. The LS3 is filled with components designed for high performance and longevity, starting with a sturdy reciprocating assembly that’s matched with L92-type rectangular-port heads and a high-lift, hydraulic roller camshaft. It all optimizes the LS3’s tremendous airflow and supports a broad torque curve.

Our LS3 crate engine comes complete, from the Camaro F-body oil pan to the ignition system. It also includes the intake manifold assembly with injectors and throttle body, water pump, balancer and 58X reluctor wheel. The Camaro F-body oil pan may not suit all installation applications. Use a vehicle-specific oil pan for original LS-powered vehicles or Chevrolet Performance’s Muscle Car Oil Pan Kit P/N 19212593 for older vehicles.
