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.
