Dodge EER specs: 167 ci (2.7L) 6-cylinder, 3.386 x 3.091 in (86 x 78.5 mm) bore and stroke, 9.7:1 compression. Rated 200 hp, 1998–2004.
The Dodge 167ci (EER) is oversquare — the 3.3858" bore exceeds the 3.0906" stroke by 9.6% — a layout that favors airflow and RPM over leverage at the crank. The 3.0906" stroke does not reach 4,000 ft/min of mean piston speed until about 7,750 RPM, so piston speed is not what limits this engine's revs — valvetrain and breathing are. Each of the 6 cylinders displaces 27.8 ci (456 cc).
9.7:1 on aluminum heads is in the range that usually runs on pump premium; aluminum sheds heat faster than iron, which makes the same number a little more forgiving.
7 factory variants share these dimensions, rated at 200 hp across 1998–2004.
