This is a continuation of a thread in tow vehilces. Not trying to start brand wars. Just looking for some comparision info on engines I'm not familiar with. Blueblazer62 stated: "The base engine is better and stronger in many ways," In what mechanical aspects are you refering to? Lots of people are familiar with the Cummins 6BT/ISB, but lets get some info on comparible Cat 6 cylinders. Heck, bring on the +/-'s for anyother I6 turbo diesel!
