Ford Vulcan 3.0 specs: 182 ci (3.0L) 6-cylinder, 3.50 x 3.15 in (88.9 x 80 mm) bore and stroke. Rated 145-150 hp, 1986–2000. Used in the Ford Aerostar. OHV.
The Ford Vulcan 3.0 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. 17 factory variants share these dimensions, rated from 145 to 150 hp across 1986–2000.
