A Powerful Turn-Key Small-Block Package and Overdrive Automatic!

The SP350/385 offers contemporary engine features on the classic Small-Block Chevy architecture. Building on the strength and power of legendary engines like the ZZ4, GM's engineers upped the ante with lightweight aluminum cylinder heads, LT-1 style pistons and new valvetrain components to create the SP350/385 with 385 hp.

This Turn-Key crate engine includes the dual-plane aluminum intake manifold, carb., distributor, water pump, damper and flexplate. Also included: starter, fuel pump, A/C compressor, alternator, front-end accessory drive kit, ignition wires, spark plugs and more. Take the guesswork out of the equation. Assemble. Install. Turn the key!

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.
