Studebaker 194ci (1965) specs: 194 ci 6-cylinder, 3.563 x 3.25 in (90.5 x 82.6 mm) bore and stroke, 8.5:1 compression. Rated 120 hp, 1965.
The Studebaker 194ci (1965) is oversquare — the 3.5625" bore exceeds the 3.25" stroke by 9.6% — a layout that favors airflow and RPM over leverage at the crank. The 3.25" stroke does not reach 4,000 ft/min of mean piston speed until about 7,400 RPM, so piston speed is not what limits this engine's revs — valvetrain and breathing are. Each of the 6 cylinders displaces 32.3 ci (530 cc).
8.5:1 is low by modern standards and generally happy on regular pump fuel.
