Dodge EGW specs: 197 ci (3.2L) 6-cylinder, 3.622 x 3.189 in (92 x 81 mm) bore and stroke, 9.5:1 compression. Rated 225 hp, 1998–2001.
The Dodge 197ci (EGW) is oversquare — the 3.622" bore exceeds the 3.189" stroke by 13.6% — a layout that favors airflow and RPM over leverage at the crank. The 3.189" stroke does not reach 4,000 ft/min of mean piston speed until about 7,550 RPM, so piston speed is not what limits this engine's revs — valvetrain and breathing are. Each of the 6 cylinders displaces 32.8 ci (538 cc).
9.5:1 is in the range that usually runs on pump premium.
4 factory variants share these dimensions, rated at 225 hp across 1998–2001.
