    Chevrolet Performance's ZZ6 delivers more power than any 350 Small-Block ever installed in a production vehicle. Rated at 405 horsepower and 406 lb.-ft. of torque, it derives its range-topping performance from unique, lightweight aluminum cylinder heads that enable optimal airflow at high rpm.

    The cylinder head casting is based on the proven Fast Burn design, with large intake runners and 2.00/1.55-inch valves. Beehive-style valve springs deliver greater high-rpm performance and durability. Their egg-shaped profiles have less reciprocating mass in motion, require less spring pressure for greater valve control and handle valvetrain stresses more efficiently. They allow the ZZ6 to rev higher to make the most of every cubic inch of air drawn through it.

    The ZZ6 also uses an aggressive hydraulic roller camshaft that supports the engine's high-rpm airflow capability while maintaining excellent low-speed drivability. This 'Base' crate engine kit includes the intake manifold, distributor, water pump, harmonic damper and flexplate - and the distinctive, racing-inspired valve covers that distinguish this crate engine as the latest in the ZZ legacy!

    Will Hedman Street Headers (#68276) fit this engine?

    Asked by: 2ndbaser
    The 68276 will not fit this engine. Hedman number 66503 should be used instead.

    Does this engine require a stall converter? If so, what stall is recommended?  Does it have a forged or cast crankshaft?

    Asked by: Jim96
    This has a steel crank in it. A convertor having 23-2500 stall would be recommended.
