The budget performer of the LS family!

Chevrolet Performance engineers have developed the LS364/450 6.0L as a value-driven foundation for builders and enthusiasts looking to give their earlier LS-powered vehicles a high-performance shot in the arm.

Starting with a strong, economical iron cylinder block and durable rotating assembly, it features the high-lift LS6 camshaft and deep-breathing LS3 aluminum cylinder heads. It’s a strong combination that provides exceptional horsepower and a broad torque band. It is also fuel injection-capable, using production-based components offered in this catalog. Additionally, the LS364/450 is designed with the early-style 24X crankshaft and 1X camshaft sensors, enabling easy retro-fit installation in early LS-powered vehicles.

We offer the LS364/450 exclusively as a long-block assembly, without the induction system, ignition system or front-end accessory drive system, allowing builders to transfer components from their early LS-powered vehicle or complete a custom build with the components of their choice. An intake manifold that matches the LS3/L92-style rectangular intake ports is required.
