The Holden V8 engine is an overhead valve (OHV) V8 engine that was produced by the Australian General Motors subsidiary, Holden between 1969 and 2000. The engine was used initially in the Holden HT series; it was later utilised in the Torana and Commodore ranges. The final iteration, the HEC 5000i, was phased out in Holden passenger vehicles upon the release of the VT II Commodore in mid 1999, which featured the Gen III V8 imported from the United States. The engine continued in the VS III Commodore utility which continued to be sold alongside the VT model until the new generation VU Ute debuted in late 2000. VS III Statesman continued with the Holden V8 engine also for a short while until the new WH Statesman was released in 1999.
In addition to being Holden's mainstream performance engine throughout its production run, it was also a popular powerplant for kit cars and specials as well as for motorsport in Holden's efforts in the Australian Touring Car Championship and the Bathurst 1000 until 1995. Australian company Repco developed and built the Repco-Holden Formula 5000 engine for Formula 5000 and other racing applications using the block and head castings of the Holden V8 as its basis. The engine featured many modifications including Lucas fuel injection and dual coil Bosch ignition and more than 150 special components designed by Repco. The lifter bore angle in the engine block is 45 degrees from the block centerline.
Initially offered in 253 cu in (4,142 cc) and 308 cu in (5,044 cc) versions, the engines were intended to be offered as part of the 1968 Holden HK range, but the project ran behind schedule and instead became part of the 1969 HT model range. In the HT, the Holden V8 sold alongside the 350-cubic-inch (5.7 L) Chevrolet Small-Block engine until 1974 with the introduction of the HJ series.
