Hyundai G6DP specs: 3.3L (203.9 ci) 6-cylinder, 92 x 83.8 mm (3.6220 x 3.2992 in) bore and stroke, 10:1 compression. Rated 365 hp. Rod ratio and piston speed.
The Hyundai G6DP is oversquare — the 3.622" bore exceeds the 3.2992" stroke by 9.8% — a layout that favors airflow and RPM over leverage at the crank. The 3.2992" stroke does not reach 4,000 ft/min of mean piston speed until about 7,250 RPM, so piston speed is not what limits this engine's revs — valvetrain and breathing are. Each of the 6 cylinders displaces 34.0 ci (557 cc).
10:1 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.
It is one of 2 engines in the Lambda II family, the smallest at 203.9 ci. Factory fitments include the Genesis G70, Genesis G80, Kia Stinger.
