  • Buick V8 engine


    The Buick V8 is a family of V8 engines produced by the Buick division of General Motors between 1953 and 1981. The first version replaced the Buick straight-eight. Displacements vary from (for the division's unique all-aluminum early 1960s engine) to for its last big block in 1976. All are naturally aspirated OHV pushrod engines, except for an optional turbocharged version of the short-lived 215 used in the 1962-63 Oldsmobile Cutlass. There were six displacements of the "Nailhead" in two generations between 1953 and 1966, varying from to ; three displacements of standard cast iron small blocks between 1964 and 1981, and and ; one of the aluminum blocks (1961-1963); and three big blocks between 1967 and 1976 and and . Some of these Buick V8s, such as the 350, 400, and 455, had the same displacements as those from other GM divisions, but were otherwise entirely different engines.

  • Oldsmobile V8 engine


    Toronado's 425 V8, the first post-war front-wheel drive V8 application. The Oldsmobile V8 refers to a series of Oldsmobile engines beginning with the advanced 1949 Rocket which were, along with the 1949 Cadillac V8, the first post-war OHV V8 engines produced by General Motors. Like all other GM divisions, Olds continued building its own V8 engine family for decades, finally adopting the corporate Chevrolet 350 small-block and Cadillac Northstar engine only in the 1990s. All Oldsmobile V8s were manufactured at plants in Lansing, Michigan. All Oldsmobile V8s use a 90° bank angle, and most share a common stroke dimension: for early Rockets, for later Generation 1 engines, and for Generation 2 starting in 1964. The , , , and engines are commonly called small-blocks. , , and V8s have a higher deck height ( versus ) to accommodate a stroke crank to increase displacement. These taller-deck models are commonly called "big-blocks", and are taller and wider than their "small-block" counterparts. The Rocket V8 was the subject of many first and lasts in the automotive industry. It was the first mass-produced OHV V8, in 1949. The factory painted "small-blocks" gold or blue (flat black on the late model ), while "big-blocks" could be red, green, blue, or bronze. As is the case with all pre-1972 American passenger car engines, published horsepower and torque figures for those years were SAE "Gross," as opposed to 1972 and later SAE Net ratings (which are indicative of what actual production engines produce in their "as installed" state - with all engine accessories, full air cleaner assembly, and full factory exhaust system in-place).
