The Buick straight-8 engine (Fireball 8) was produced from 1931 to 1953 and sold in Buick automobiles, replacing the Buick Straight-6 engine across the board in all models in 1931. Like many American automobile makers, Buick adopted the straight-eight engine in 1931 as a more powerful alternative to the previous engines.
