8.0L Magnum V10 Explained

Chrysler's Magnum Series engine is, more or less, the second generation of the LA-series small block. In early form the Magnum engine was used exclusively in Dodge trucks such as the Dakota, Ram, Durango and Ram Van. As quickly as it came out, the Jeep Grand Cherokee also got them as an option. The production run of the Magnum engine series was from 1992-2003. Aftermarket support for the Magnum series has grown over the years and with proper maintenance, they will last forever.

Most folks don't realize that the 'Magnum' term in the 8.0L (488 CID) Magnum V10 name is not just marketing-speak. Starting with a 5.9 V8, two cylinders were added and the stroke of the crankshaft was increased. The V10 was only used in the Ram 2500 and Ram 3500 trucks starting in the 1994 model year. In fact this engine is also the basis for the Dodge Viper V10. The truck engine made 310 horsepower and 450 ft/lbs of torque. Gas mileage of only 8-10 mpg is common with these trucks.

8.0 Bore x Stroke= 4.00" x 3.88"
