context_page_description: The Oldsmobile V8, also referred to as the Rocket, is series of engines that was produced by Oldsmobile beginning in 1949. The Rocket, along with the 1949 Cadillac V8, were 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, 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: 3.4375 in for early Rockets, 3.6875 in for later Generation 1 engines, and 3.385 in for Generation 2 starting in 1964. The 260 cu in, 307 cu in, 330 cu in, 350 cu in and 403 cu in engines are commonly called small-blocks. 400 cu in, 425 cu in, and 455 cu in V8s have a higher deck height to accommodate a 4.25 in stroke crank to increase displacement. These taller-deck models are commonly called "big-blocks", and are 1 in taller and 1.5 in 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.
context_section_description: The Generation II V8 ended production in 1990. The company later introduced a new vehicle, the Oldsmobile Aurora, with a new generation V8. Based on the Cadillac Northstar engine, this, called Aurora, was a DOHC design.
  From the 1950s through the late 1970s, each GM division had its own V8 engine family. Many were shared among other divisions, but each design was unique:
  Buick V8 engine
  Cadillac V8 engine
  Chevrolet Small-Block engine
  Chevrolet Big-Block engine
  Pontiac V8 engine
  Holden V8 engine
  GM later standardized on the later generations of the Chevrolet design:
  GM LT engine - Generation II small-block
  GM LS engine - Generation III/IV small-block
