The Chevrolet 350-cubic-inch engine was produced from 1967 to 2003. Originally available in the 1967 Camaro, it was last used in Chevy and GMC light-duty trucks, vans and SUVs. It is still available from GM's aftermarket parts dealers as a crate engine.

Design

The basic design of the small block Chevy (SBC) was engineered in the mid-1950s with a 90-degree "V" configuration -- two banks of 4 cylinders. The 350ci engine used the same basic platform, but with larger internal dimensions. The cylinder bore was 4 inches and the piston stroke was 3.48 inches, yielding a displacement of 349.85 cubic inches (rounded up to 350).

Applications

In 1967, the 350 SBC was only available in the Camaro and became an option on other GM vehicles over the next few years. In the late 1990s, it was only available in trucks, vans and SUVs until its eventual production stop.

Power Output

Power output varied widely. At its peak, the 1970 Camaro Z28 LT1 350 engine produced 350 horsepower and 380 foot-lbs. of torque. (The 1970 Corvette LT1 engine produced 370 hp.) By the mid 1970s, emission requirements reduced output to as little as 125 hp for California versions of the engine.
