Buick V6 engine

The Buick V6 is an overhead-valve V6 developed by the Buick division of General Motors and first introduced in 1962 as the 198 cubic inch Fireball engine. It was derived from Buick's 215 cubic inch aluminium V8 family, the same family that became the Rover V8. General Motors later developed the 231 cubic inch 3.8 litre version, widely known simply as the 3800, which made the Ward's 10 Best Engines of the 20th Century list and passed 25 million units built, making it one of the most-manufactured engines in automotive history. GM sold the design to Kaiser-Jeep in 1967 and bought it back from American Motors in early 1974 after the oil crisis. The engine has a cast-iron block and two-valve iron heads, was built at Flint, Michigan and also in Australia, and was the first six-cylinder designed only for Buick since the Buick straight-six ended in 1930. It powered the Skylark, Riviera, Century and other models.
