2500 or 3500 engine swap into 4500

I have a 2009 Dodge Ram 4500 Cab and Chassis, the engine started knocking and I am looking to put a used engine in it. I have talked to several junk yards that say you can't put the 2500 or 3500 engine into a cab and chassis truck. I don't see what the major difference is? Can you put the regular truck engine into the cab and chassis? I feel like they are just trying to charge me extra for the cab and chassis engine.

Thanks

The long block is the same. The tuning is different. I have heard that the injector nozzles are slightly smaller in the 4500/5500 trucks, I cannot verify that.

Swap a good used good long block in from a light truck, it will work just fine.
