Seems you want information heres some for ya .
The 5.9 cummins was put in a lot of medium duty trucks , for some reason they do not put the cold start system on them but other wise they are the same motor . Oddly enough they are detuned as well in the medium duty trucks .
Dodge ran the motor in 99 at 235 hp , but only 215 hp with the auto trans . Ford put it in a lot of medium duty trucks , Chevy used cats until they put the duramax in them . and international trucks run there own .
Dont bother with IHC motors if this is for a wheeler , they larger and heaver then you would want . If this is for some sort of tow rig then a IHC DT 466 is the best small diesel truck motor you can buy bar none .
For smaller like the 5.9 again best in its class .
