The truck versions of the 903 were dogs. We have one in a tanker at my fire company. 57 MPH on a long flat.

The engines are capable of big power, I heard of marine applications at over 1000HP, but heat seems to be the problem. There is no way to dissipate the excess heat in a truck application.

Would steer clear of the Cummins 903 engine.  There's a real good reason why they are not used in anymore-just were not long lasting enough.  Granted the military has some vehicles that were built around the 903 so Cummins is still building the 903 for the military.  But remember-if the military gets 2000 hours out of an engine, that's all they require.  I don't think 80-100,000 miles is enough miles for an engine to last, especially in this day and age of 1 million mile truck engines.  Good Luck, TomC

yeah, it appears they're pretty widely used in bradley tanks and also marine/motoryacht applications. couldn't find much of anything on their use in the mdt/hdt truck industry.
