The Classic 350 to Drive Your Project!

Chevrolet Performance’s 350 HO crate engine is a smart and powerful alternative to rebuilding. In fact, with its high-flow cylinder heads, a strong hydraulic camshaft and a four-barrel carburetor, it’s rated at 333 horsepower and 381 lb.-ft. of torque. That’s more power than almost every 350 engine ever offered in a production vehicle.

The 350 HO is built on a sturdy, all-new block with four-bolt mains. It’s topped with a set of Vortec  cylinder heads, and the contemporary hydraulic flat-tappet camshaft supports a broad power band, while requiring 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 & air cleaner.

The 350 HO is also available in “Deluxe” and “Base” configurations. See next page for information.
