From a brief wikipedia browse, the most reliable source of info in the world lol.
The Buick V6, initially marketed as Fireball at its introduction in 1962, is a large V6 engine used by General Motors. The block is made of cast iron and all use two-valve-per-cylinder iron heads, actuated by pushrods....
The LN3 was replaced by the 3.8 L (3791 cc, 231 cu in)[3] L27 in 1991-1992 and produced 170 horsepower (130 kW) from 1992 onward, this engine was referred to as the Series I 3800. In Australia, the LN3 was also replaced by the L27 by Holden who used the engine in their series 2 (1991) VN Commodore range. However, the Australian L27 retained the LN3's one piece upper intake and lower plenum. Power was still boosted to 127 kW (170 hp) for the Holden L27. The L36 made its debut in 1995.
