Affordable high-performance with everything you need to get running

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 163-cc intake runners, raised exhaust ports, and tight, 58-cc 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 — including an air conditioning compressor, alternator, and more!

If you want to finish off the engine yourself, try the ZZ4 350 Base engine (P/N 24502609) at a lower price. It includes only the intake manifold, distributor, water pump, damper, and flexplate.
