The '''122 engine''' was designed by [[Chevrolet]] and was used in a wide array of [[General Motors]] vehicles. The ''122'' was similar to the first two generations of the [[General Motors 60° V6 engine]]; sharing [[cylinder bore]] diameters and some parts.{{citation needed|date=May 2014}} The ''122'' was available in the U.S. beginning in 1982 for the [[GM J platform]] compact cars and [[Chevrolet S-10|S-series]] trucks.

For the [[GM J platform|J-cars]], it evolved through 2002 when it was replaced by GM's '''[[L850 engine|Ecotec]]''' line of [[DOHC]] [[Straight-four engine|4-cylinder]] engines. In the [[Chevrolet S-10|S-10]] related models, it evolved through 2003 and was known as the '''Vortec 2200'''. Production ceased consistent with the replacement of the [[Chevrolet S-10|S-series]] trucks with the [[GM GMT platform#GMT 355|GMT 355]] sub-platform.
