Ford 232ci (1982–1997) specs: 232 ci (3.8L) 6-cylinder, 3.811 x 3.386 in (96.8 x 86 mm) bore and stroke. Rated 140-230 hp, 1982–1997.
The Ford 232ci (1982–1997) is oversquare — the 3.811" bore exceeds the 3.3858" stroke by 12.6% — a layout that favors airflow and RPM over leverage at the crank. The 3.3858" 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. A rod ratio of 1.746 is in the range most production engines fall in. Each of the 6 cylinders displaces 38.7 ci (634 cc).
It is one of 17 engines in the Ford 232ci family, all of them 232 ci — the differences between them are in compression, heads and rating, not displacement. 18 factory variants share these dimensions, rated from 140 to 230 hp across 1982–1997.
