The tag should show a torque rating of 600. If it does not you most likely have a 2004 Dodge Cummins 5.9L Diesel.

The 5.9 L ISB (Interact System B) is one of the largest straight-6 engine ever produced for light truck vehicles, and the improved high output 600 version was on the Ward's 10 Best Engines list for 2004.

One unusual feature of the ISB is that it is a multi-valve push rod engine design. The engine displaces 5883 cc with a 102.1 mm bore and 119.9 mm stroke. A turbocharger output in the high-compression (17.2:1 in recent versions) Diesel. It is an all-iron engine with forged steel connecting rods, an assembled camshaft, and a cast aluminum intake manifold. The engine is produced in Columbus, Indiana.

There have been several versions of the 5.9 L ISB featured in the Dodge Ram. The BT 5.9 was first introduced to Dodge Rams in 1989. The Cummins engine in 1991.5 got an inter cooler. In 1994, the engine changed over to a Bosch model P7100 inline-style injection pump from the previous Bosch VE series rotary pump. Midway through model year 1998, the engine which would now be known as the ISB, was redesigned as a 24 valve model to meet updated emissions requirements and introduced the Bosch VP44 rotary injection pump (featuring electronic control) to the Dodge application. It produced 235 hp (175 kW) at 2700 rpm and 460 ft·lbf (625 Nm) from 1600 rpm to 2700 rpm when paired with a manual transmission, but was slightly downrated when used with automatics.

In 2001, an optional high output (HO) version of the ISB was introduced, producing 245 hp (183 kW) at 2700 rpm and 505 ft·lbf (686 Nm) from 1600 rpm to 2700 rpm when paired with a heavy duty six-speed transmission, the NV5600. The ISB from previous years remained available, and automatic-equipped engines were now rated the same as manuals.

For the 2003 model year, the Cummins was introduced with Bosch high pressure common rail fuel injection, again increasing power output. Midway through the 2004 model year, the Cummins 600 was introduced, producing 325 hp (242 kW) at 2900 rpm and 600 ft·lbf (813 Nm)at 1600 rpm. This high torque output gives the engine its name, and also offers a high specific output of 102 ft·lbf (138 Nm) per liter of displacement.

A 610 version, new for the 2005 model year, pushes torque to 610 ft·lbf (827 Nm).
