Land Rover M62B44 specs: 4.4L (268 ci) 8-cylinder, 92 x 82.7 mm (3.6220 x 3.2559 in) bore and stroke, 10:1 compression. Rated 282 hp, 2003–2005.
The Land Rover M62B44 is oversquare — the 3.622" bore exceeds the 3.2559" stroke by 11.2% — a layout that favors airflow and RPM over leverage at the crank. The 3.2559" stroke does not reach 4,000 ft/min of mean piston speed until about 7,350 RPM, so piston speed is not what limits this engine's revs — valvetrain and breathing are. Each of the 8 cylinders displaces 33.5 ci (549 cc).
10:1 is in the range that usually runs on pump premium.
It is one of 4 engines in the Land Rover 268ci family, all of them 268 ci — the differences between them are in compression, heads and rating, not displacement. 3 factory variants share these dimensions, rated at 282 hp across 2003–2005.
