3.9/4.0
The 3.9 L Rover V8, a bored-out version of the original 3.5 L engine, was used in several Land Rover vehicles, TVRs, and the MG RV8.
Land Rover used a 3,946 cc (240.8 cu in) version of the Rover V8 throughout the 1990s. Bore was increased to 94.0 mm (3.70 in) and stroke remained the same at 71.0 mm (2.80 in). The engine was revised in 1995 (and thereafter referred to as a 4.0 to differentiate it from the earlier version, although displacement remained the same at 3,946 cc) with a new intake and exhaust system, extra block ribbing, revised pistons, and larger cross-bolted main-bearings. The 1995 4.0 produced 190 hp (142 kW) and 236 lb·ft (320 N·m) .
Production of the 4.0 ended in 2003. The final version of the engine, used in the 2003 Land Rover Discovery, produced 188 hp (140 kW) at 4,750 rpm and 250 lb·ft (340 N·m) at 2,600 rpm.

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 (TVR 390SE) 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.
