Crate Engine - 6.2L LS3 430HP
Crate Engine - LS3 - 430 HP - GM LS-Series
A Contemporary Classic
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.
