Land Rover 241ci (1989–2002) specs: 3.9L (241 ci) 8-cylinder, 94 x 71.1 mm (3.7008 x 2.8000 in) bore and stroke. Rated 178-190 hp, 1989–2002.
The Land Rover 241ci (1989–2002) is oversquare — the 3.7008" bore exceeds the 2.8" stroke by 32.2% — a layout that favors airflow and RPM over leverage at the crank. The 2.8" stroke does not reach 4,000 ft/min of mean piston speed until about 8,550 RPM, so piston speed is not what limits this engine's revs — valvetrain and breathing are. Each of the 8 cylinders displaces 30.1 ci (494 cc).
21 factory variants share these dimensions, rated from 178 to 190 hp across 1989–2002.
