Good Cam for 69 340

This has probably been asked a million times but with all new options for cams, I will ask again. So I will be putting my matching 340 back in my GTS. It is 40 over and all stock. 202 X heads etc. I want to put a new more potent cam in it with the stock rocker set up. I will be adding a 750 carb and a RPM Air Gap intake, Electronic ignition and Doug's Headers. I don't need anything too radicle. It is a 4 speed with 3:23's.
