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.

SP502/605 Deluxe 19421200

One of GM's Most Popular Big-Blocks is Elevated with More Power!

With the popular and proven ZZ502 as its starting point, Chevrolet Performance engineers took its capability to the next level to create the more powerful SP502/605 Deluxe, which is rated at a strong 605 hp and 580 lb.-ft. of torque. It’s the sort of power for your vintage muscle car, hot rod or classic truck that comes only from the incomparable Big-Block family.

New, higher-compression pistons, a new hydraulic-roller camshaft, CNC-ported oval-port heads and more drive the SP502/605’s greater output — and this all-new Big-Block crate engine is distinguished with all-new cast aluminum valve covers based on the striking, contemporary design introduced on the ZZ632.

It is offered in a Deluxe kit that includes an 850-cfm carburetor and aluminum intake manifold, HEI distributor, plug wires, starter, water pump and balancer. It also includes a new-design five-quart oil pan.
