Introducing the Pace Performance Dyno Tuned 416 HP ZZ6 Turn-Key Crate Engine :
In addition to the already stout ZZ6, Turn Key offering, We Fully Dyno Test and custom tune this version to make even more HP than Advertised from GM. We take a Hand Built AED carburetor and replace the stock unit for a full Dyno Session and Custom Tuning. We even include a custom fuel rail to feed the hand built AED double pumper!

Chevrolet Performance’s new ZZ6 delivers more power than any 350 Small-Block ever installed in a production vehicle.

Dyno'd at at 416 hp and 422 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, damper and flexplate – and the distinctive, racing-inspired valve covers that distinguish this crate engine as the latest in the ZZ legacy!
