SP350/385 Turn-Key Crate Engine

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 beehive-style 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.
