What Cam would you suggest with this

A 2000 stall is nothing for a Chrysler. You have to understand, Chrysler used higher stall speeds in their stock converters than the other domestic makers of the time. A stock low stall Chrysler converter would stall around 1200-1500. The factory high stall about 1000 more than that, so when you say "2000 stall" you are still in stock converter territory.

As for a camshaft, a good off the shelf cam would be something like the Comp 265DEH, but as reasonable as custom cams are, I would not go off the shelf, nor would I go Comp. I just gave that as an example of a decent grind.
