ROVER (Wikipedia) Golden years
The 1950s and '60s were fruitful years for the company, with the Land Rover becoming a runaway success (despite Rover's reputation for making up-market saloons, the utilitarian Land Rover was actually the company's biggest seller throughout the 1950s, '60s and '70s), as well as the P5 and P6 saloons equipped with a 3.5L (215ci) aluminium V8, the design and tooling of which was purchased from Buick, and pioneering research into gas turbine fuelled vehicles.
In 1970, Rover combined its skill in producing comfortable saloons and the rugged Land Rover 4x4 to produce the Range Rover, the first car to combine off-road ability and comfortable versatility. Powered by the ex-Buick V8 engine, ....

(Wikipedia) Aluminum 215 ("Rockette")
From 1961 to 1963 Oldsmobile manufactured its own version of the Buick-designed, all-aluminum 215 engine for the F-85 compact, known as the Rockette. This was a compact, lightweight engine with a dry weight of only 350 lb (159 kg). The Oldsmobile engine was very similar to the Buick engine, but not identical: it had larger combustion chambers with flat-topped (rather than domed) pistons, six bolts rather than five per cylinder head, slightly larger intake valves, and the valves were actuated by independently-mounted rocker arms instead of shaft-mounted rocker arms. With an 8.75:1 compression ratio and a two-barrel carburetor, the Olds 215 had the same rated hp, 155 hp (116 kW) @ 4800 rpm, as the Buick 215, with 220 ft·lbf of torque at 2400 rpm. With a four-barrel carburetor and 10.25:1 compression, the Olds 215 made 185 hp (138 kW) @ 4800 rpm and 230 ft·lbf (312 N·m) (@ 3200 rpm.
The basic Buick/Olds 215 V8 went on to become the well known Rover V8, remaining in production until the 1990s. The Rover V8 however utilized Buick-style pistons, heads, and valvetrain gear.
The Oldsmobile Rockette engine block formed the basis of the Repco 3 liter engine used by the Brabham team to win the 1966 and 1967 Formula One world championships. The early Repco engines produced up to 300 bhp, and featured new SOHC cylinder heads and iron cylinder liners. The 1967 and later versions of the Repco engine had proprietary engine blocks.
NOTE - I could not find a Wikipedia story on the Buick version as the Olds version above - but maybe I just tired of the search...

There were differences between the Buick and Olds 215, but Rover bought the Buick version tooling - and the rest, as they say, is history. Apparently the "American" 215 is quite in demand for MGB owners in North America who want more oomph - and lots of parts are still produced in Merrie Olde.
