Ford 1957 292 212HP specs: 292 ci (4.8L) 8-cylinder, 3.75 x 3.30 in (95.3 x 83.8 mm) bore and stroke. Rated 212 hp, 1957. Used in the Ford Fairlane. OHV.
The Ford 1957 292 212HP is oversquare — the 3.75" bore exceeds the 3.3" stroke by 13.6% — a layout that favors airflow and RPM over leverage at the crank. The 3.3" stroke does not reach 4,000 ft/min of mean piston speed until about 7,250 RPM, so piston speed is not what limits this engine's revs — valvetrain and breathing are. Each of the 8 cylinders displaces 36.5 ci (598 cc).
It is one of 9 engines in the Ford 292ci family, all of them 292 ci — the differences between them are in compression, heads and rating, not displacement.
