i just bought an 01 dodge single cab cummins cause the purple one that i believe i had a picture on here of got stolen. and i bought this one with 58,000 miles on it. but was wanderin if theres a way to tell if its an ho for sure. the guy told me it was and it feels alittle stronger than my other truck when it was stock. so if u have any input to how to figure it out please let me know. bombing in progress.

 

If it has an Automatic Transmission then its a SO.

 

Correct me if I'm wrong but I believe that the 2001 H.O. (245hp/505tq) was only mated with the 6-speed manual NV5600 transmission. My understanding is that the 235 hp S.O. engine came with either the auto or the 5-speed NV4500 transmission options.

There is another way to tell. On the driver's side of the engine closest to the radiator is a nameplate that is vertical. It gives the motor hp rating and some other info.

 

maybe there is a letter or number in the vin. . that's the way the newer ones are
