Mitsubishi 6G74 SOHC specs: 3.5L (214 ci) 6-cylinder, 93 x 85.8 mm (3.6614 x 3.3780 in) bore and stroke. Rated 200 hp, 1997–2002.
The Mitsubishi 6G74 SOHC is oversquare — the 3.6614" bore exceeds the 3.378" stroke by 8.4% — a layout that favors airflow and RPM over leverage at the crank. The 3.378" stroke does not reach 4,000 ft/min of mean piston speed until about 7,100 RPM, so piston speed is not what limits this engine's revs — valvetrain and breathing are. Each of the 6 cylinders displaces 35.7 ci (584 cc).
It is one of 2 engines in the Mitsubishi 214ci family, all of them 214 ci — the differences between them are in compression, heads and rating, not displacement. 6 factory variants share these dimensions, rated at 200 hp across 1997–2002.
