The Foundation for a High-Revving 350 Small Block!

The new 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 V-8 engines for nearly half a century.

Building on the strength and power of legendary Small Block 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.

The Chevy SP350 Base crate engine kit includes the dual-plane aluminum intake manifold, distributor, water pump, damper and flexplate.

This part replaces old P/N 19333157 and 19417624.
