General Motors began producing the 60° V6 engine in 1980, as a 2.8 liter (173 cubic inches) iron-head engine. In 1993, the aluminum-head 3100 (3.1 liter) went into production. Its configuration was an iron engine block, a single cam-in-block pushrod layout with aluminum heads. Production for china stopped in 2010, while the rest of the world saw its production end in 2005.
