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.
