Mazda Ford Vulcan 3.0 OHV V6 specs: 3.0L (182 ci) 6-cylinder, 88.9 x 80 mm (3.5000 x 3.1496 in) bore and stroke. Rated 147-154 hp, 1994–2008.
The Mazda 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).
14 factory variants share these dimensions, rated from 147 to 154 hp across 1994–2008.
