Cummins 5.9 engine 24 valve, 1998.5 - 2002 ? Removed from running truck 180,000 miles Approx. I seen it running, no blow - by. That said it has been in my shop. You also get the engine stand, and Amsoil by- pass oil filtration system. The engine has head studs, I have not pulled the oil pan to inspect lower end. This engine is a 53 block . Call please with questions, I will sell the engine ECU , injection pump & injector's for $ 400 additional I also have an NV 4500 5 speed, for additional $ 500 it will need bearings I believe, I put a new one in my truck, & don't have the time to look into it. Take care
