Direct from the Camaro SS to your project vehicle

 

The LS3 6.2L is the 430-hp standard engine in the Chevrolet Corvette and is a fantastic combination of high technology and uncompromising performance. Our LS3 crate engine comes complete, from the Corvette specific oil pan to the ignition system. It also includes the EFI intake manifold assembly with injectors and throttle body, exhaust manifolds, water pump, balancer, 58X reluctor wheel, and 14-inch automatic-transmission flexplate.

 

Inside, the LS3 is filled with components designed for high performance and longevity. The aluminum block is filled with a sturdy reciprocating assembly that combines with L92-type rectangular-port heads to deliver a 10.7:1 compression ratio. A high-lift, hydraulic roller camshaft delivers a whopping 0.551-inch of lift on the 2.16-inch intake valves and 0.522-inch lift on the 1.59-inch exhaust valves, enhancing the LS3’s tremendous airflow and broad torque curve.

 

The Corvette oil pan doesn’t 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 versions.
