Chrysler 8.0L Magnum V10

8.0L V10 Specs and Information

The 8.0L Magnum V-10 was offered in the 1994 to 2003 Dodge Ram 2500 and 3500. While this engine is dimensionally similar to the V-10 found in the Dodge Viper, it is an entirely different engine platform with a cast iron engine block and cast iron cylinder heads. The engine was rated at 300 horsepower at its introduction, but power was increased to 310 horsepower for the 1999 model year. All model years produced a respectable 450 lb-ft of torque at a relatively low 2,400 rpm. The 8.0L V10 was offered as an alternative to the Cummins turbodiesel and standard V8 gasoline engine.

Dodge's 8.0L V10 is part of the Chrysler LA engine family and is based on the 360 CID V8 platform, but with a lengthened stroke and two additional cylinders. The V10's longer stroke length contributes to its low end torque - 450 lb-ft at a mere 2,400 rpm. The engine was mated to the Chrysler 47RH automatic transmission for 1994 and 1995 model years, the 47RE for 1996 to 2002 model years, and the 48RE for 2003, the last year that the engine was offered. A New Venture NV4500 5 speed manual transmission was also available for 2003, however a manual transmission was not available in earlier model years. The 8.0L Magnum V10 was discontinued following the 2003 model year, being phased out in favor or more sophisticated and fuel efficient engine platforms. While the V10 made respectable horsepower and torque, the market quickly outgrew its large size and aging technology.
