The Holden V8 engine, also known in some circles colloquially as the Iron Lion (versions from 1969–1985 were also often called the Holden 253 or Holden 308 up until 1974 then Holden 4.2 and Holden 5.0, depending on their capacity), is an overhead valve (OHV) V8 engine that was produced by the Australian General Motors subsidiary, Holden (GMH), between 1969 and 2000. The engine was initially fitted to the Holden HT series in 1969 and was later utilised in a series of updated versions in the Torana and Commodore ranges. The final iteration, the heavily revised HEC 5000i, was phased out of Holden passenger vehicles with the release of the VT Series II Commodore and the WH Statesman and Caprice in June 1999, both of which featured the 5.7L Gen III V8 imported from the United States. However, the engine remained in production for a little while longer and continued to be available in the Commodore VS Series III utility (which sold alongside the VT sedan and wagon as no similar vehicle was available in that range) until the new generation VU Ute debuted in late 2000. In addition to being Holden's mainstream performance engine throughout its production run, higher performance versions were fitted to limited-edition vehicles available through Holden Dealer Team Special Vehicles (HDT) and later Holden Special Vehicles (HSV). It was also utilised within limited production vehicles from other manufacturers as well as in kit cars. The engine has a successful history in various forms of motorsport, most notably in Touring Car racing through the Australian Touring Car Championship and the Bathurst 1000 until 1995, as well as in Formula 5000 and other racing applications such as Sports Sedans. It can also be found in Australian powerboats fitted with inboard engines, especially those used for water skiing.
