to the UK to act as a consultant. The Rover V8 has long been a relatively common engine for kit car use in Britain, much as the Chevrolet small-block V8 is for American hot rod builders (though many British hot rods have traditionally used four cylinder engines, like the Ford Pinto and Crossflow units). Even in the US there is a strong contingent of builders who select the Buick or Rover aluminium V8 engine for use in small sporty cars like the MGB . The 1964 Buick iron-block engine had aluminium cylinder heads, 3.75 bore and a longer 3.4" stroke crankshaft, which with modification can be used with the Buick 215 or Rover engine blocks to produce a high-output, very light weight V8 with displacement of up to about . The 300 crank, after machining the mains to the 215 size in the 215 block yields . Traco in the USA were prominent builders of such engines. The British made engines were run on two SU carburettors, initially HS6 then HIF6 and HIF44 variants (14 years), then two CD175 Stromberg carburettors (2–3 years), Bosch L-Jetronic (7–8 years, aka Lucas 4CU Flapper), then Hitachi Hotwire (5 years, aka Lucas 14CUX), then the GEMS system (many years) and finally Bosch Motronics for 2 years. The engine is still cast now (2011), in an improved version, by Coscast in Birmingham, UK. As well as appearing in Rover cars, the engine was sold by Rover to small car builders, and has appeared in a wide variety of vehicles. Rover V8s feature in some models from Morgan +8, TVR, Triumph TR8, Land Rover and MGB V8, among many others. By the early 2000s, the Rover V8 had become uncompetitive with other V8 engines in its class. It produced between 80-100 hp less than more modern V8 engines, it used much more fuel compared to newer V8s, and used an aged 16-valve pushrod architecture, while V8 engines made by other luxury automakers often used dual overhead-cams and 32 valves. After Land Rover switched to the BMW M62 V8 in the 2003 Range Rover, and the Land Rover Discovery 3 switched to Jaguar AJ-V8 engines, the last mass-produced Rover V8 was made in May 2004, after 37 years of production, and just under 1 million engines produced. The 2004 Land Rover Discovery was the last mass-produced vehicle to use it. The last Rover-badged vehicle that used the
