Genuine OE GM Engine - 19418137

THE CLASSIC 350 SMALL-BLOCK WITH MODERN FEATURES As part of Chevrolet Performance's new line of Street Performance engines, the SP350 offers contemporary engine features on the classic Small-Block architecture, for a unique blend of the low-rpm torque 350 engines have always been known for, and is also higher-rpm performance comparable. The SP350's unique capability lies in its lightweight aluminum cylinder heads, which feature a valvetrain with beehivestyle valve springs, similar to the design of the high-revving LS engine family. They enable greater high-rpm performance and durability, allowing the engine to rev higher and maximize the airflow capability of the heads - all without sacrificing the 350's signature torque. Our SP350 Turn-Key package comes complete with the distributor and balancer installed. The carburetor, starter, fuel pump air conditioning pump, alternator, Front-End Accessory Drive Kit and more are also included, ready to bolt on.
