The ZZ4 350 crate engine is Chevrolet Performance’s original affordable crate engine. In Turn-Key form, it comes with everything you need to get it running in your project vehicle. High-flow aluminum heads are the keys to the ZZ4’s robust 355 hp and 405 lb.-ft. of torque. They boast 163cc intake runners, raised exhaust ports and tight, 58cc combustion chambers that enhance compression and power.

The heads feature 1.94/1.50-inch valves for efficient performance. The rest of the ZZ4 350 is comprised of premium materials, including a brand-new, four-bolt block, forged steel crankshaft, high-silicon pistons and a hydraulic roller camshaft. It also includes an aluminum intake, Holley four-barrel carburetor and HEI distributor, as well as a starter, water pump, fuel pump and front-end accessory drive kit

The 350/290 HP Deluxe combines Chevrolet Performance’s most popular crate engine with an aluminum intake manifold* and chrome dress-up kit to create one of the most stylish and value-driven engines on the market. The chrome dress-up parts include the valve covers (with push-in
breathers and “T-bar”-style hold-downs), timing cover and air cleaner.

The 350/290 crate engine is also available without the manifold and chrome dress-up kit. Use this even more economical version to build the final combination to your specifications.
