Chevrolet Performance 5.7L 350 HO 333 HP Turnkey Long Block Crate Engines

The Chevrolet Performance 5.7L 350 HO 333 HP Turnkey long block crate engines are assembled with all-new parts and high-flow heads, giving you more power than just about any production-spec small block ever installed at the factory. Designed, engineered, and tested to stringent Chevrolet specifications, these cast-iron blocks with four-bolt main caps is the foundation for the 350 HO, which is topped with iron Vortec heads fitted with 1.94/1.50 in. valves. In addition, durable rotating assembly has aluminum pistons that deliver a 9.0:1 compression ratio.
