Jeep 360 specs: 360 ci (5.9L) 8-cylinder, 4.08 x 3.44 in (103.6 x 87.4 mm) bore and stroke, 8.2:1 compression. Rated 175 hp. OHV. Rod ratio and piston speed.
The Jeep AMC V8 (360) 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).
8.2:1 on iron heads is low by modern standards and generally happy on regular pump fuel.
It is one of 7 engines in the AMC V8 family, sitting between the 304 ci and 401 ci members. Factory fitments include the Jeep Grand Wagoneer, Jeep J-Series Truck, Jeep Cherokee (SJ).
