Ford SHO V8 specs: 207 ci (3.4L) 8-cylinder, 3.244 x 3.13 in (82.4 x 79.5 mm) bore and stroke, 10:1 compression. Rated 235 hp, 1996–1999.
The Ford SHO V8 is close to square: 3.2441" bore against 3.1299" stroke, within 3.6%, which splits the difference between a high-revving layout and a torque layout. The 3.1299" stroke does not reach 4,000 ft/min of mean piston speed until about 7,650 RPM, so piston speed is not what limits this engine's revs — valvetrain and breathing are. Each of the 8 cylinders displaces 25.9 ci (424 cc).
10:1 is in the range that usually runs on pump premium.
4 factory variants share these dimensions, rated at 235 hp across 1996–1999.
