Ford SHO specs: 182 ci (3.0L) 6-cylinder, 3.504 x 3.15 in (89 x 80 mm) bore and stroke, 9.8:1 compression. Rated 220 hp, 1989–1995. Used in the Ford Taurus.
The Ford 182ci (SHO) is oversquare — the 3.5039" bore exceeds the 3.1496" stroke by 11.2% — a layout that favors airflow and RPM over leverage at the crank. The 3.1496" stroke does not reach 4,000 ft/min of mean piston speed until about 7,600 RPM, so piston speed is not what limits this engine's revs — valvetrain and breathing are. Each of the 6 cylinders displaces 30.3 ci (497 cc).
9.8:1 is in the range that usually runs on pump premium.
It is one of 5 engines in the Ford 182ci family, all of them 182 ci — the differences between them are in compression, heads and rating, not displacement. 7 factory variants share these dimensions, rated at 220 hp across 1989–1995.
