The Classic 350 330HP Vortec Crate Engine

Forget rebuilding! Our 350 HO is 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: 333 hp and a satisfying 381 lb.-ft. of torque. It’s affordable power with dependability you can count on.

A cast-iron block 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-inch valves. Its durable rotating assembly has aluminum pistons delivering a 9.0:1 compression ratio, while a hydraulic flat-tappet camshaft requires no periodic lash adjustments.

As one of our Turn-Key crate engines, the 350 HO Turn-Key comes with the intake manifold and distributor installed.

It also includes the carburetor and spark plug wires (not installed).
