Ford Vulcan 3.0 OHV V6 specs: 182 ci (3.0L) 6-cylinder, 3.50 x 3.15 in (88.9 x 80 mm) bore and stroke. Built 1992–1994. Used in the Ford Tempo. OHV.
The Ford Vulcan 3.0 OHV V6 is oversquare — the 3.5" bore exceeds the 3.1496" stroke by 11.1% — a layout that favors airflow and RPM over leverage at the crank. The 3.1496" stroke does not reach 4,000 ft/min of mean piston speed until about 7,600 RPM, so piston speed is not what limits this engine's revs — valvetrain and breathing are. Each of the 6 cylinders displaces 30.3 ci (497 cc).
It is one of 5 engines in the Ford 182ci family, all of them 182 ci — the differences between them are in compression, heads and rating, not displacement. 3 factory variants share these dimensions across 1992–1994.

| Years | 1992–1994 |
| Bore/stroke character | 1.111 — oversquare — bore exceeds stroke, which favours higher RPM and larger valves |
|---|---|
| Mean piston speed at 6,000 RPM | 3,150 ft/min — conservative for a street engine |
| Displacement per cylinder | 30.3 ci |
