e/Buick Straight-8 engine

Information
has gloss	eng: The Buick Straight-8 engine (Fireball 8) was produced from 1931 to 1953 and sold in Buick automobiles. Like many American automobile makers, Buick adopted the straight-8 engine in 1931 as a more powerful alternative to the previous inline-6 engines. However, unlike most other car makers at the time, Buick had been using a valve-in-head OHV overhead valve design or I-head since its inception and continued this practice in their inline-8 designs. The engine was sold in different displacements depending on the model of car and the year and was constructed upon two distinct ( possibly more ) block castings. The smaller displacement versions internally resembled the inline Chevrolet straight six, with additional cylinders. The large block version (used in large chassis models such as the Roadmaster) was considerably heavier and this weight adversely affected vehicle performance and handling.
