Run away fast. I hate those things. Especially with a maxitorque trans. Constant wire harness issues, injector cup issues, injector issues, water pump problems, ect ect.
This gem of a d13 had a air compressor go bad with a load of black top on. A cummins or cat could be chan changed out before the load set up. Not on this chitball. Its a 6-10 hour job to do that. No thanks
That being said, id go 370 with short rubber and 390 if your runnin tall

More problems than the Cummins 2250 and Detroit DD’s?
