The Chevrolet Performance SP350/385 Base crate engine incorporates modern technologies such as a beehive-type valve springs to take the classic 350 Small-Block to new levels of high-rpm performance ? without sacrificing the signature torque that has made it the benchmark of SBC V-8 engines for nearly half a century.

Building on the strength and power of legendary engines like the ZZ4, GM’s engineers upped the ante with proven Fast Burn aluminum cylinder heads, LT-1 style pistons and new valvetrain components.

It’s all backed by the 4L65-E four-speed overdrive automatic, which enables great highway cruising performance and fuel economy, while retaining good off-the-line performance with the steep first gear. It is tough as nails too, with the durability of hardened internal parts and five-pinion gearsets.
