Small-Block Crate Engines - 350 HO Turn-Key

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 Chevrolet Performance’s Turn-Key crate engines, the 350 HO Turn-Key comes with the intake manifold and distributor installed. It also includes the carburetor, front-end accessory kit, chrome air cleaner, starter, and spark plug wires (some installation required)
