Lincoln 302 Windsor V8 specs: 302 ci (5.0L) 8-cylinder, 4.00 x 3.00 in (101.6 x 76.2 mm) bore and stroke, 8.4:1 compression. Rated 130 hp. OHV.
The Lincoln 302 Windsor V8 is oversquare — the 4" bore exceeds the 3" stroke by 33.3% — a layout that favors airflow and RPM over leverage at the crank. The 3" stroke does not reach 4,000 ft/min of mean piston speed until about 8,000 RPM, so piston speed is not what limits this engine's revs — valvetrain and breathing are. Each of the 8 cylinders displaces 37.8 ci (619 cc).
8.4:1 on iron heads is low by modern standards and generally happy on regular pump fuel.
It is one of 4 engines in the Windsor family, the smallest at 302 ci. Factory fitments include the Lincoln Continental, Lincoln Town Car, Lincoln Versailles and 6 others.
