Based on the value-driven 350 HO crate engine, Chevy’s engineers swapped the flat-tappet camshaft for a hydraulic roller and added the latest Small-Block intake manifold design. Together, they help build more power across the rpm band – 357 horsepower and 407 lb.-ft. of tire-turning torque. | The SP350/357 leverages the strength of a strong rotating assembly secured in a brand-new block with four-bolt mains, along with economical Vortec iron cylinder heads. It’s a durable assembly designed to offer years of highperformance excitement at an excellent value.

Chevrolet Performance’s new ZZ6 delivers more power than any 350 Small-Block ever installed in a production vehicle | Rated at 405 hp 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
