Ford Kent Crossflow 1.6 specs: 98 ci (1.6L) 4-cylinder, 3.187 x 3.055 in (81 x 77.6 mm) bore and stroke. Built 1978–1980. Used in the Ford Fiesta.
The Ford Kent Crossflow 1.6 is close to square: 3.1874" bore against 3.0551" stroke, within 4.3%, which splits the difference between a high-revving layout and a torque layout. The 3.0551" stroke does not reach 4,000 ft/min of mean piston speed until about 7,850 RPM, so piston speed is not what limits this engine's revs — valvetrain and breathing are. Each of the 4 cylinders displaces 24.5 ci (401 cc).
It is one of 6 engines in the Ford 98ci family, all of them 98 ci — the differences between them are in compression, heads and rating, not displacement. 3 factory variants share these dimensions across 1978–1980.
