    The LS3...A New Classic!

    Free Shipping!

    As the standard engine in the fifth-generation Camaro SS and C6 Corvette, the high-revving, deep-breathing LS3 6.2L is poised to go down in history as one of Chevrolet's best and most versatile engines. It's no surprise that enthusiasts and builders have made it one of the most popular LS swap engines. It's a brute of a small block with 376 cubic inches just waiting for you.

    The LS series engine has broken new ground for efficiency and performance from a pushrod platform engine. The LS3 is filled with components designed for high performance and longevity. In the bottom end, the aluminum 6-bolts/main block features 4.065-inch bores and 3.622-inch stroke. A nodular iron crankshaft, powdered metal rods, and aluminum pistons (10.7:1 compression ratio) round out a rev-happy short block. The sturdy reciprocating assembly combined with L92-type rectangular-port heads deliver a 10.7:1 compression ratio. A high-lift, hydraulic roller camshaft complements the LS3's tremendous airflow capability and enhances its broad torque curve. Out-of-the-crate Horsepower is 430, with an impressive 425 lb.-ft. torque.

    This LS3 crate engine comes complete from the SS-specific oil pan to the ignition system. It also includes the intake manifold assembly with injectors and throttle body, exhaust manifolds, water pump, balancer, 58x reluctor wheel and 14-inch automatic-transmission flexplate. The SS oil pan doesn't suit all applications. So you will need to use the vehicle specific oil pan for original LS-powered vehicles or Chevrolet Performance's Muscle Car Oil Pan Kit (p/n 809-19212593) for older vehicles.

    Will this fit in a 1994 chevy lumina z34 ?

    No, the Lumina is a front wheel drive car, these engines are designed for rear wheel drive applications.
