if it has gauges then i would bet he has it modified. if it has big tranny oil pan and temp gauge i would think it has had tranny work done to it( but ask) ask if the KDP has been tabbed. i would ask if any front end work has been done ( known dodge weak point) pull the tranny dip stick and smell it to see if it smells like burnt toast. sound like a good deal if it checks out. also see if the timing has been bumped as a part of his modifications. if he has the tranny cooler and deep pan i would say he has used the rig to pull some heavy loads. just my 2 cents!!!!

 

if you want it and it sounds good,starts good, feels good when you drive it and doesnt look bad and everything else looks good oil,coolant etc etc i would buy that damn thing right now for 5 grand
