I'm sure Rusty has built more engines than me but I've run the HD Mopar stamped steel rockers, prod push rods, and the old purple DC 292/.509 hydraulic cam in my 440 without issue in regards to compatibility, shifting at 6200 rpm. Car ran mid-12's in my 4200# Charger. Maybe I got lucky with the tolerances? Dunno.
I believe that 292/.509 is more cam than you are looking for as the idle is pretty rough (like I like!). The old DC 284/.484 cam in a 440 would be more tame at idle and still be a good performer. I used it in my 383 that was in the Charger prior to the 440. It went 13.0's but never got a 12-sec timeslip from it. The idle in it was not as rowdy as the 292 cam but still rough in the smaller displacement and short-stroke 383. It would be quite a bit more tame in the longer stroke, bigger displacement 440.
You can look up the specs on those DC cams and find something comparable from some of the other cam companies. I'm personally a big fan of Bullet Cams simply due to my satisfaction with the custom SFT I got from them for the avatar and the plethora of lobes they have available.
Good luck!
