context_page_description: The General Motors 60° V6 engine family was a series of 60° V6 engines which were produced for both longitudinal and transverse applications. All of these engines are 12-valve cam-in-block or overhead valve engines, except for the LQ1; which uses 24 valves driven by dual overhead cams. These engines vary in displacement between 2.5 and 3.4 litres and have a cast-iron block and either cast-iron or aluminum heads. Production of these engines began in 1980 and ended in 2005 in the U.S., with production continued in China until 2010. This engine family was the basis for the GM High Value engine family. These engines have also been referred to as the X engines due to their first usage in the X-body cars.
  This engine is not related to the GMC V6 engine that was designed for commercial vehicle usage.
context_section_description: The second generation, still 2.8 litres (2,837 cc), was introduced in 1987. It used aluminum heads with splayed valves and an aluminum front cover. It was produced exclusively for transverse, front-wheel drive use.
  The next year, Chevrolet introduced a full-production long-stroke 3.1 L; 191.3 cu in (3,135 cc) version in the Pontiac 6000 STE AWD, with a 89 mm (3.5 in) bore and 84 mm (3.31 in) stroke compared to the 2.8 which shared the same bore, however with a 76 mm (2.99 in) in stroke. It was produced simultaneously with the 2.8 L (2,837 cc) in various compact and midsized vehicles until 1990, when the 2.8 L (2,837 cc) was dropped. MPFI was used on both, and a full-production turbo version was available on the 3.1 L (3,135 cc). An even higher displacement DOHC 3.4 L (3,350 cc) LQ1 was also developed, and eventually, the new GM High Value engine family followed. Production of OHV Generation II engines ended in 1994 after the introduction of the Generation III in 1993.
