Land Rover 256ci (1993–1995) specs: 4.2L (256 ci) 8-cylinder, 94 x 77 mm (3.7008 x 3.0315 in) bore and stroke. Rated 200 hp, 1993–1995.
The Land Rover 256ci (1993–1995) is oversquare — the 3.7008" bore exceeds the 3.0315" stroke by 22.1% — a layout that favors airflow and RPM over leverage at the crank. The 3.0315" stroke does not reach 4,000 ft/min of mean piston speed until about 7,900 RPM, so piston speed is not what limits this engine's revs — valvetrain and breathing are. Each of the 8 cylinders displaces 32.0 ci (524 cc).
It is one of 2 engines in the Land Rover 256ci family, all of them 256 ci — the differences between them are in compression, heads and rating, not displacement. 3 factory variants share these dimensions, rated at 200 hp across 1993–1995.
