Im new to the diesel world and dont know much about them. Ive always owned gassers and now im wanting a Cummins have for awhile now. Which size motor should i go with and what mods should i look for and stay away from?

 

If it has service records fear not. The engines are good for 500K. Buy it if the price is right.

 

Thanks. What mods should i look for and what mods to stay away from?
