350 HO Base Crate Engine

All the same power-building elements as the Turn-Key and Deluxe versions

At this price, and with these features and warranty... why rebuild? The Chevrolet Performance 350 HO Base is a budget-conscious long-block assembly packed with all-new parts and high-flow heads, giving you more power than just about any production-spec Small-Block Chevy ever installed at the factory with 333 hp and 381 lb.-ft. of torque. It’s affordable power with dependability you can count on.

A brand-new 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 camshafprovides trouble-free cruising. Add your own intake and carb, ignition, etc.

You won't go broke finishing off your project car with our 350 HO Base crate engine!

It's packed with all the features you need to get a reliable 333 hp and 381 lb.-ft. of torque from a dependable, time-tested combination of Chevrolet Performance parts. Of course, all the components used in this engine are brand new - not remanufactured parts like the competition is trying to sell you. Designed by GM in-house engineers to give you maximum return for your hot rod dollar, the Chevy Performance 350 HO Base crate engine is a great choice for your small block crate engine needs.

The 350 HO is based on a tough, Chevy four-bolt block that holds a strong nodular iron crankshaft, good rods, and aluminum pistons. The high-lift camshaft gives this crate engine its own unique, aggressive idle. The cam is based on the same one found in 1965-67 Corvette 327 engines, but it has even more lift and duration.
