Most Cummins distributors can sell you a new ISB 24 valve Dodge application engine for about $6K. There is one draw back, the engines are new not rebuilds but have no warranty. The engines come complete: wiring harness, ECM, starter, Fly wheel, battery cables (no grounds), Fuel Sys, engine mounts, oil and filters. They are a true drop in engine, the only thing missing was the A/C and Alt. What happened, I was told, most of all the new engines that were in warehouses for distribution for the Dodge dealers were send back to Cummins when the 03 came out. A few were kept for warranty purpose. Cummins does not want to have them in their warehouse so they are selling them to the distributors in the same way they got sold to Dodge, NO WARRANTY. At work we have done two engines, they had all the new up-dates that were made while they were at the warehouses. I been thinking of buying one but I'm in the process of trying to get a 4X4 3500 to turn into a service truck and my 2500 is a 12 valve. Call your nearest Cummins Distributor and not a Cummins Dealer for more information.
