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.
