Chevrolet Performance LS3 6.2L 430 HP Crate Engines 19434636

Transform your street rod with LS power from Chevrolet Performance! This LS3 6.2L is the 430 hp standard engine in the 5th Generation Chevy Camaro SS and the all-new RWD Chevy SS. It’s a fantastic combination of high technology and uncompromising performance. The crate engine comes complete, from the Chevy Sedan SS specific oil pan to the ignition system—and includes the EFI intake manifold assembly with injectors and throttle body, water pump, balancer, and 58X reluctor wheel. The aluminum block is filled with a sturdy reciprocating assembly that combines with the aluminum L92-type rectangular-port heads to deliver a 10.7:1 compression ratio. A high-lift, hydraulic roller camshaft—with 0.551 in. of lift on the 2.16 in. intake valves and 0.522 in. lift on the 1.59 in. exhaust valves—enhances the LS3’s tremendous airflow and broad torque curve.
