The Chrysler 360 Magnum is a 5.9 L (5,899 cc, 360 cu·in) natural aspirated V8 90° four-stroke liquid-cooled internal combustion gasoline engine, manufactured by Chrysler Corporation from 1992 to 2003.
A 99.3 mm (3.91 in) cylinder bore and 84.0 mm (3.31 in) piston stroke give the 5.2 L (360 cu in) Magnum V6 engine a total of 5,899 cm3 of displacement. The compression ratio rating is 9.1:1.
The 360 Magnum engine produced 234 PS (172 kW; 230 HP) at 4,000 rpm of maximum horsepower and 447 N·m (45.6 kg·m, 329.4 ft·lb) at 3,250 rpm of maximum torque. In 1998 the engine was upgraded, this version produced 248 PS (183 kW; 245 HP) at 4,000 rpm of horsepower and 454 N·m (46.3 kg·m, 334.6 ft·lb) at 3,250 rpm of torque. The R/T version produced 249.0 PS (183.0 kW; 245.0 HP) at 4,000 rpm and 468.0 Nm (47.7 kg·m; 345.4 ft·lb) at 3,250 rpm.
The Chrysler 360 Magnum V8 engine features:
- Eight-cylinder V-type 90°
