Modern technology drives this classic 350 small-block!
Developed with contemporary technologies, including a high-rpm valvetrain, the ZZ6 Turn-Key offers a modern twist on the classic 350 Small-Block, delivering more than 400 horsepower and more than 400 lb.-ft. of torque!
The ZZ6 uses updated Fast Burn cylinder heads with beehive-style valve springs inspired by the LS engine family–a feature that enhances high-rpm capability to support more power than any factory-produced 350 engine ever installed in a Chevrolet production vehicle. The unique, tapered shape of the valve spring allows for the use of a smaller spring retainer, which reduces the reciprocating mass of the valvetrain, resulting in better valve dynamics.
The turn-key engine package includes the carburetor, distinctive valve covers and matching air cleaner, distributor, front-end accessory kit, starter, and spark plug wires (some installation required).
