BUDGET PERFORMER BLENDS BEST OF LS ENGINE FAMILY

Chevrolet Performance engineers have developed the LS364/450 as a value-driven foundation for hot rod 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, the LS 6.0L features the high-lift LS6 camshaft and the deep-breathing LS3 aluminum cylinder heads. Its a strong combination with exceptional horsepower and a broad torque band. It is also fuel injection-capable, using production-based components offered in this catalog.

The LS364/450 is designed with the early-style 24X crankshaft and 1X camshaft sensors, enabling easier retro-fit installation in early LS-powered vehicles, including 19982002 Camaros, C5 Corvettes, 19992006 full-size trucks and SUVs, and other LS 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.

No matter which vehicle you drop the LS364/450 into, its combination of horsepower and value will push your project vehicle to the next level of performance!

Cover too loose.
Size: 300A Fuse Holder
Nice looking, decent quality, versatile for different gauges. My only complaint with this holder is the cover doesn’t stay on very well, bought 3, and all 3 pop off easily, you will need to zip tie on.
