An updated version of the popular LS2, Chevrolet’s LS3 V8 engine was featured in the 2008-2013 Corvette, 2009 Pontiac G8, and the 2010-Present Camaro and SS. The LS3 is capable of producing over 430 horsepower, featuring higher flowing cylinder heads and an overall improved manufacturing efficiency. The LS3 can be found in classic street rods to muscle cars to even short track series race cars as a late model engine swap. Whether you’re just upgrading one of these cars or building from the ground up, Speedway Motors carries all the aftermarket performance parts you need to fully equip your LS3 engine. Be sure to turn to the folks at Speedway Motors, your one-stop shop for everything LS.
