The performance numbers for the reengineered 5.9-liter “600” Cummins diesel engine in the 2004 1/2 Dodge Ram 2500/3500 are not only awesome, they’re the best of any heavy-duty pickup:



Kudos Dodge beating up on both Chevy and Ford.

In developing the new “600,” Cummins and Dodge made numerous other improvements or changes to the engine:

• Air inlet redesigned to block hot engine air from entering, reducing the intake charge by 30 to 40 degrees.
• Intake resonator re-engineered for increased airflow
• Larger compressor on Holset turbocharger
• Engine cooling improved with new fan assembly and mounting fan shroud to engine for more efficient airflow through radiator
• Upgraded intercooler
• Upgraded exhaust valves
• Tailpipe increased to 4-inch diameter
• Improved sealing and gasket materials
• Oil-change intervals are now 15,000 miles (vs. 7,500 for competition).
• Holset turbocharger gets bigger compression side
• Switch to electronic control of wastegate
• Upgrades to exhaust manifold
• Revised intake ports in cylinder head
• New piston bowl geometry
• Different spray pattern from injectors
