GMC L96 specs: 364 ci (6.0L) 8-cylinder, 4.00 x 3.622 in (101.6 x 92 mm) bore and stroke. Rated 352-360 hp, 2010–2020. Used in the GMC Sierra HD. OHV.
The GMC 364ci (L96) is oversquare — the 4" bore exceeds the 3.622" stroke by 10.4% — a layout that favors airflow and RPM over leverage at the crank. The 3.622" stroke puts mean piston speed at 4,000 ft/min around 6,650 RPM, which is where a production bottom end is generally considered at its limit. A rod ratio of 1.684 is in the range most production engines fall in. Each of the 8 cylinders displaces 45.5 ci (746 cc).
It is one of 8 engines in the GMC 364ci family, all of them 364 ci — the differences between them are in compression, heads and rating, not displacement. 25 factory variants share these dimensions, rated from 352 to 360 hp across 2010–2020.
