The Classic Small Block with Modern Features
The SP350/385 Turn Key offers contemporary engine features on the classic Small-Block architecture. It’s a unique blend of the low-rpm torque that 350 engines have always been known for and higher-rpm performance.
The SP350/385’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 SP350/385 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.
Replaces old P/N 19417623.
Chevrolet Performance Crate Engines include a 24-month or 50,000-mile (80,000 kilometer) limited warranty.
