ZZ4 350 Turn-key

As far as crate engines go, this one is a winner. The ZZ4 350 Turn-Key crate engine has been one of our most popular high performance crate engines since we started GM Performance Parts. Its legendary status is based on an incredible performance level that is stone cold reliable. We’ve packed the ZZ4 350 crate engine with a forged steel crankshaft, hypereutectic pistons, hydraulic roller camshaft and lifters, and aluminum cylinder heads. The ZZ4’s Corvette-derived high-performance heads feature high velocity intake runners and D-shaped exhaust ports to promote efficient and unobstructed flow through the engine, providing strong power and torque at all RPM levels.
The ZZ4 350 is delivered with an aluminum dual-plane intake manifold, HEI distributor, cast iron water pump, damper, and flexplate. Our Turn-Key ZZ4 350 crate engine also ships with all the parts you need to get it running. That includes an accessory drive package, fuel pump, chrome air cleaner kit, Holley 750-cfm carburetor, starter, and spark plug wires.
The ZZ4 comes to you with a full 355 horsepower and 405 lb.-ft. of torque. With its high level of performance and durability, it could very well be the perfect crate engine, able to meet the needs of car builders from all phases of the motorsports world.
