Lincoln Windsor (1980–1992) specs: 302 ci (5.0L) 8-cylinder, 4.00 x 3.00 in (101.6 x 76.2 mm) bore and stroke, 9:1 compression. Rated 225 hp, 1980–1992.
The Lincoln Windsor (1980–1992) 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. A rod ratio of 1.697 is in the range most production engines fall in. Each of the 8 cylinders displaces 37.8 ci (619 cc).
9:1 on iron heads is low by modern standards and generally happy on regular pump fuel.
It is one of 9 engines in the Windsor family, the smallest at 302 ci. 13 factory variants share these dimensions, rated at 225 hp across 1980–1992.

Factory specification sheet.
| Bore/stroke character | 1.333 — oversquare — bore exceeds stroke, which favours higher RPM and larger valves |
|---|---|
| Mean piston speed at 6,000 RPM | 3,000 ft/min — conservative for a street engine |
| Rod ratio | 1.697 — moderate — the range most production V8s fall in |
