Dodge LA 360 specs: 360 ci (5.9L) 8-cylinder, 4.00 x 3.579 in (101.6 x 90.9 mm) bore and stroke. Rated 150-195 hp, 1974–1988. Used in the Dodge Ramcharger.
The Dodge LA 360 is oversquare — the 4" bore exceeds the 3.5787" stroke by 11.8% — a layout that favors airflow and RPM over leverage at the crank. The 3.5787" stroke puts mean piston speed at 4,000 ft/min around 6,700 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).
