Camshaft recommendation for my specific Slanty build?

Howdy! Looking for an experienced recommendation for my build. First, the hardware;

1965 Plymouth Barracuda

Stock reman Slant six 225:
-Cliffy (not Offy!) Hyper-Pak
-Edelbrock 1403 with small jets & fat rods (live at 6200ft so leaned out)
-Stock exhaust manifold
-2.5" mandrel exhaust/glasspack muffler
-No PS or AC
-Electronic ignition (Mopar chrome box)

Driveline:
-904 Automatic Stock
-8 3/4" rear with 2.93/LSD
-4 wheel disc brakes, manual Wilwood style master

I'm looking for a midrange-RPM torque-centric cam, I have a vintage 13' camper trailer I'll be towing on occasion. Driving-wise, I prefer road course style driving power, not really drag/off the line. I plan on keeping the 2.93 for now, might go 3.55/3.73 down the line.

Whose cam & what grind(s?) should I lean toward for my build? What's going to give the most CFM flow improvement with that Hyper-Pak and still be streetable? I don't run Power brakes so a drop in vacuum/lopey idle is fine. I'm hoping someone will be speaking from experience running a Hyper Pak and similar 4bbl on a stock block. I've got NO interest in grinding heads, porting, polishing or anything too involved right now. Cams are an afternoon project, wanna keep it that way :)

Thanks in advance! Here's my baby, she's coming along nicely...
