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,
front-end accessory kit, chrome air cleaner, starter, and spark plug wires
(some installation required).
