A legendary foundation for performance

Building on the strength and power of its predecessors, Chevrolet Performance engineers have upped the ante with a revised cylinder head design, new valvetrain components, and more to create the SP350/385 Base—a 385-horsepower 350 with loads of low-end torque. In fact, the SP350/385 Base Small-Block engine produces at least 405 lb-ft of torque by only 3600 rpm for a thrilling feeling of immediate performance.

The new, lightweight aluminum cylinder head casting is based on the proven Fast Burn design, with large intake runners and 2.00/1.55-inch valves. New beehive-style valve springs enable greater high-rpm performance and durability, as the egg-shaped springs have less reciprocating mass in motion, require less spring pressure for greater valve control, and handle valvetrain stresses more efficiently.

As with all of Chevrolet Performance’s Small-Block crate engines, the SP350/385 Base is built with a brand-new block with four-bolt mains. It also features a forged-steel crankshaft, an aggressive hydraulic roller camshaft, and durable, high-silicon pistons. Unique valve covers distinguish this new crate engine at a glance, too.

The base crate engine package includes an aluminum intake manifold, distributor, water pump, damper, flexplate, and more.  

Connect & Cruise Powertrain System

Connect & Cruise Crate Powertrain Systems provide factory-matched engine-and-transmission combinations that include specially calibrated controllers and wire harnesses designed for retrofit installations in older vehicles. Connect and Cruise packages are available for a wide variety of crate engines which can be paired with an automatic or manual transmission.
