History


The Rover V8 began life as the Buick 215, an all-aluminium engine introduced in 1960 for the 1961 US model year. The compact engine was lightweight, at just 144 kg (318 lb), and capable of high power outputs: the most powerful Buick

 version made 215 hp (both numbers SAE gross). Based on sales volume and press reports, the engine was a success. Buick produced 376,799 cars with this engine in just three years. A comparable number of Oldsmobile 215 engines were produced. In addition, some Pontiac

 models were fitted with the Buick 215, leading to the nickname "BOP 215" for the engine (BOP standing for Buick/Oldsmobile/Pontiac). The aluminium engine was relatively expensive to produce, however, and it suffered problems with oil and coolant sealing, as well as with radiator

 incompatible with aluminium. As a result, GM ceased production of the all-aluminium engine after 1963, although Buick retained a similar iron engine[1964-1980], as well as a V6 derivative[1962-2008] which proved to have a very long and successful life.

In January 1964 Rover gave American operations head J. Bruce McWilliams permission to investigate the possible purchase of an American V8 engine for Rover cars. It is usually said that McWilliams first saw the Buick V8 at the works of Mercury Marine

, where he was discussing the sale of Rover gas turbines and diesel engines to the company (Mercury did indeed use the Land Rover diesel engine in marinised form). However, it seems likely that McWilliams was aware of the Buick engine before this. In any case, McWilliams realised that the lightweight Buick V8 would be ideal for smaller British cars (indeed, it weighed less than many straight-4

 engines it would replace.) McWilliams and William Martin-Hurst began an aggressive campaign to convince GM to sell the tooling, which they finally agreed to do in January 1965. Retiring Buick engineer Joe Turley moved to the UK to act as a consultant.

 and the Chevy Vega. Note also that the 1964 Buick iron-block 300 cid engine had aluminium cylinder heads and a longer stroke crankshaft which with minor modifications 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 300 cubic inches. The 300 crank in the 215 block yields 260 cid.

The British made engines were run on two SU carburettors (14 years), then two Stromberg carburettors (2-3 years), Bosch L-Jetronic (7-8 years, a.k.a. Lucas 4CU Flapper), then Hitachi Hotwire (5 years, a.k.a. Lucas 14CUX

It is also interesting to note that the "Rover V8" based on the Buick design was not the first V8 produced by Rover. When the Rover Co was having engineering differences of opinion with the development of the Whittle turbine engine, the Wilks' did a deal with Rolls-Royce to swap technologies. The turbine engine project went to Rolls-Royce and Rover Co took over the V12 Meteor production used in the Centurion Tank

With the introduction of the Rover SD1 in 1975, the engine was dramatically improved with the 'rope' oil seals replaced with poly items and the spark plug dimensions changed.

  • 1998 Land Rover Defender 50th Anniversary Limited Edition


In the early 1980s TVR approached Andy Rouse with a view to using his race-developed 3.9L variant of the V8 in their Rover-powered 350i 'wedge'; Rouse had successfully campaigned a Rover SD1 with a modified V8 on the track. For a number of reasons (primarily cost) Rouse's version was not used, but the concept was passed to alternative engineering firms which resulted in a rare variant of the 3.9. This unit has 93.5mm cylinder bores (instead of Rover's own 94mm that was introduced some years later) and thus has a capacity of 3,905cc. Flat-topped pistons and high-lift camshaft gave a compression ratio of 10.5:1. TVR claimed 275 bhp as the output and whilst this is generally disregarded by aficionados, a healthy 3,905 cc engine will produce in excess of 240 bhp. Once a reproducible specification had been determined, the bulk of engine production was undertaken by North Coventry Kawasaki (NCK), which company was subsequently purchased by TVR to become their in-house engine division known as TVR Power.
About 100 cars were built with the 3,905 cc engine; TVR's later '400' offering being based on the then-current Range Rover 4L of 3,946 cc.

Applications:
  • 1986–1989 TVR 390SE

4.2


Land Rover extended the 3,946 cc engine for the top LSE specification of the Classic Range Rover. The 4.2 L engine had a displacement of 4275 cc, and used the crankshaft castings from the failed "Iceberg" diesel engine project. Bore remained the same at 94 mm (3.7 in), while stroke increased to 77 mm (3 in).

4.3


For the Griffith and Chimaera, TVR Power, a Coventry-based subsidiary of sportscar maker TVR, built a Rover V8-version with a 4280 cc displacement using the 77 mm (3 in) stroke crankshaft as per the Land Rover 4.2 engine, but with a 94 mm (3.7 in) bore size. The so-called 'pre-cat' versions of the Griffith predominantly used this engine, although a 4.0 litre version was also available. The Chimaera was introduced with choice of 4.0 and 4.3 litre engines. A small number of 'Big Valve' versions, sporting modified cylinder heads with 43 mm (1.7 in) intake and 37 mm (1.5 in) exhaust valves and a more radical camshaft profile, found their way to early Griffiths and Chimaeras.

Around 1993, a number of Westfield SEight models were equipped with a John Eales-built 4.3 litre engine.

. The bore was 88.9 mm (3.5 in) and the stroke was 88.9 mm (3.5 in), making it a square engine. The block deck height was extended and longer conrods were fitted 158.75 mm (6.3 in) between centres. This rare engine produced 200 hp (149 kW) and 280 ft•lbf (380 N•m) and although export (to the UK) versions were planned, the closure by British Leyland of their Australian operations in 1975 precluded the widespread application of this engine.

In 1996, Land Rover enlarged the Rover V8 to 4552 cc. The bore remained the same size as the previous 4.0 at 94 mm (3.7 in), but the engine was stroked by 10.9 mm (0.429133858267717 in) giving 82 mm (3.2 in) in total. Output was 225 hp (168 kW) and 280 ft•lbf (380 N•m).

The last mass-produced application of the Rover V8 was the Land Rover Discovery, up until the vehicle was redesigned in 2005. It is still used by some hand-built sports cars built by some independent manufacturers.
