Buick Straight 6 engine

The Buick Straight 6 was an engine manufactured by Buick from 1914-1923. Engines from 1914-1916 are known as Series 50 engines and 1916-1923 were known as the Series 40. They were OHV, like their previous engines, as Buick had been using overhead valve engines since their beginning in 1899. The engine also had the starter and the alternator driven by one belt. The engine also did not have a removable cylinder head meaning Pistons had to come out of the bottom of the engine. They had a displacement of 255 Cubic inches.
