Chevrolet Performance 350ci/400HP ZZ5 Base Engine
Product images may differ from actual product appearance.
The Chevrolet Performance ZZ5 350 Base Engine utilizes the solid foundation of the ZZ4 HO Short Block and adds the updated Fast Burn Cylinder Heads to produce more horsepower, 400HP @ 5600 RPM, than any production muscle car or Corvette small block Chevy engine! The base crate engine package includes an aluminum intake manifold, distributor, water pump, damper, flexplate and more.
Just like the proven Fast Burn engine, the ZZ5 350 engine features lightweight aluminum cylinder head castings with large intake runners and 2"/1.55" valves. The beehive-style valve springs enable greater high-rpm performance and durability, as they require less spring pressure for greater valve control and efficiency. Better low end torque can also be expected from the ZZ5 producing at least 300 lb.-ft of torque by only 1500 rpms. It comes as no surprise that this engine is the perfect choice for enthusiasts that crave the thrilling feeling of immediate power!
