Chevy 350 Crate Engines

All Chevy 350 Crate Engines start with a spanking new cast-iron block. Modern technologies such as large intake runners and beehive-style valve springs are then incorporated. GM Performance engineers have continually enhanced and refined the performance and capability of its 350 small-block offerings. These powerful, tough crate engines are a great alternative to rebuilding your tired two-bolt block.

Chevrolet introduced the world to the very first small-block V8 in 1955. (By the way, if you like history, check out this post from Karl Kustoms.) Since that time Chevy 350 Crate Engines have powered generations of vehicles on the street and on the track. 350 small-blocks have dominated the industry, with Chevy at the forefront.

The 2017 Chevy Performance lineup features more than a dozen 350 engines. On the Karl Kustoms site, you’ll find 350/290’s, 350 HO’s, Ram Jet 350’s, SP350/357’s, SP350/385’s, ZZ6’s, and the CT350 racing engine.

A new offering in the Chevy 350 engine lineup is the SP350/357 (357 hp). The Base, Deluxe, and Turn-Key models are designed as affordable performers for just about any budget. These 350 engines take the strength of a strong rotating assembly and match it with modern valvetrain technology for high-rpm capability.


The Chevy 350/385 engine manifests a revised cylinder head design and new valvetrain components to provide 385 hp and loads of low-end torque. The Base and Turn-Key models also feature a hydraulic roller camshaft, forged steel crankshaft, high-silicon pistons, and unique valve covers.


Chevrolet Performance proudly introduces the newest member of the small-block family, the ZZ6 engine – the ultimate 350 for your project. Available as Base and Turn-Key models, Chevy engineers have pushed the classic 350 small-block to 405 hp.


For budget-conscious racers, Chevy offers the CT350 engine. It is based on the popular 350 HO high-performance street crate engine and delivers 350 hp from a classic 350 cubic-inch combination. It’s dependable, provides competitive performance and low maintenance, which allows you to focus on what’s important – the driving!

Over the years, Chevy 350 Crate Engines have been used in sports cars and station wagons, commercial vehicles, boats, and even airplanes (in extremely modified form). Hands down, it is the most widely used small-block engine of all time. Chevrolet engineers have been pushing the limits of these engines for more than 60 years, and continue to create new ways to amplify power, value, and durability.
