The same engine also has a main page: Chevrolet LH7.
GMC LH7 specs: 98 ci (1.6L) 4-cylinder, 3.138 x 3.154 in (79.7 x 80.1 mm) bore and stroke. Built 2018–2019. Used in the Chevrolet Cruze and GMC Terrain.
The GMC 98ci (LH7) is close to square: 3.1378" bore against 3.1535" stroke, within 0.5%, which splits the difference between a high-revving layout and a torque layout. The 3.1535" 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 4 cylinders displaces 24.5 ci (401 cc).
2 factory variants share these dimensions across 2018–2019.
