GMC LCV specs: 150 ci (2.5L) 4-cylinder, 3.465 x 4.00 in (88 x 101.6 mm) bore and stroke. Rated 200 hp, 2015–2022. Used in the GMC Canyon. DOHC.
The GMC 150ci (LCV) is undersquare — the 4" stroke exceeds the 3.4646" bore by 13.4% — a layout that trades peak RPM for leverage and torque low in the range. The 4" stroke puts mean piston speed at 4,000 ft/min around 6,000 RPM, which is where a production bottom end is generally considered at its limit. Each of the 4 cylinders displaces 37.5 ci (615 cc).
8 factory variants share these dimensions, rated at 200 hp across 2015–2022.
