Can I switch my 350 Chevy engine to a 6.2 diesel?

Do some research online and over at the Dodge diesel forum. I'd bet money that somewhere there's a shop that routinely installs Cummins diesel engines and tranny combo's into former gassers. It won't be cheap. You may find it less expensive to sell your gasser and buy a good used used diesel truck. But if you're set on the swap, somewhere you'll find what you're looking for. Good luck.

Happy camping!!! See y'all down the road!!!:)
