Jeep AMC 360 2-bbl specs: 360 ci (5.9L) 8-cylinder, 4.08 x 3.44 in (103.6 x 87.4 mm) bore and stroke. Rated 175-245 hp, 1971–1983. Used in the Jeep Gladiator.
The Jeep AMC 360 2-bbl is oversquare — the 4.08" bore exceeds the 3.44" stroke by 18.6% — a layout that favors airflow and RPM over leverage at the crank. The 3.44" stroke puts mean piston speed at 4,000 ft/min around 7,000 RPM, which is where a production bottom end is generally considered at its limit. Each of the 8 cylinders displaces 45.0 ci (737 cc).
It is one of 15 engines in the AMC V8 family, sitting between the 304 ci and 401 ci members. 11 factory variants share these dimensions, rated from 175 to 245 hp across 1971–1983.
