    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.

    I have a 1996 Firebird, with 6-speed manual trans, 4:10 gears. Would you recommend this LS3 to replace the stock LT1 ? would I need an adapter plate to mount the trans. to the motor? what other crate engines could you recommend?

    Asked by: TC96
    You will need to make a number of modifications to make this work properly - Please call our tech line for assistance 1-800-345-4545 ext 2001

    Will this engine fit 1966 c10 with stock oil pan? Also what is needed to hook up to 700 r 4 trans?

    Asked by: Rich b
    The 2nd oil pan included would be the one you need to use. To use an older GM trans with a LS motor you need 2 things, a flexplate and a crank spacer, part # JEGS 601080K.

    What oil pan do you recommend to fit in my 1957 Chevy 210? The car will be a daily driver and road cruiser, no racing.

    The pan shown with this engine will work nicely. This is the pan part number by itself - Part Number: 809-19212593
