When was gm 3.8 liter engine produced?

Answer 1

I suspect you mean the transversely mounted 3800. This modified version of the LD5 came into production in mid-1984. The LD5 This engine was first introduced in 1978 when GM began to market the 231 cubic inch as the 3.8 liter as metric engine sizes became common in the United States. Earlier sized models go back as far as the Buick v6, initially marketed as "Fireball" at its first introduction in 1962.
