Jeep AMC V8 (1971–1991) specs: 360 ci (5.9L) 8-cylinder, 4.08 x 3.44 in (103.6 x 87.4 mm) bore and stroke. Rated 144-195 hp, 1971–1991.
The Jeep AMC V8 (1971–1991) 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. 22 factory variants share these dimensions, rated from 144 to 195 hp across 1971–1991.
