Dodge 8.0L Magnum V-10

Dodge 8.0L V-10 Engine Specs, History, Power Ratings, & Comparisons

Dodge introduced the 8.0L Magnum V10 to the Ram 2500/3500 engine lineup for the 1994 model year. At the time, the engine produced far more torque than any competitors gasoline engine. Additionally, originally producing 300 horsepower and 450 lb-ft of torque, the V10 offered performance superior to that of the 5.9L Cummins turbodiesel. However, the V10 could not match the Cummins' fuel economy potential nor did its torque curve peak nearly as early. For the 2001 model year, the 5.9L Cummins passed the V10 in torque ratings while the V10 continued to offer significantly higher horsepower. The engine was ultimately retired following the 2003 model year for reasons that included the engine's relatively poor fuel economy.

The V10 is often identified as a 5.9L Magnum (360 CID gas engine) with two additional cylinders, however this is a misleading description. Although the designs of the engine are similar and they share a 4.00 inch cylinder bore, the V10 has a fairly longer 3.88 inch stroke. The Magnum V10 is not to be confused with the 8.0L V10 offered in the Dodge Viper - the engines are entirely different. The truck engine did not produce nearly as much horsepower as the original Viper V10, although it nearly matched the Viper in torque.

The Magnum V10 featured a relatively low 8.4 to 1 compression ratio and was designed to run on regular 87 octane gasoline. For the 1995 model year the engine was coupled to the 47RH 4 speed automatic or NV4500 5 speed manual transmission. 1996 - 2002 model year engines utilized Chrysler's 47RE automatic transmission or the NV4500 manual gearbox. In the engine's final year of production, it featured Chrysler's 48RE 4 speed automatic transmission or the New Venture NV4500.
