Comp Cams 21-406-5, it's a special order shelf cam. It used to be a stocking cam, the "275DEH" and it is the meanest sounding daily-driver B-motor cam with the broadest power band that I'm aware of. Easy on springs (use Comp #911s) and works with stock rockers. Use a stock 11" converter and hopefully 3.23+ gears. Doesn't have to have headers but will work with them as well. Wicked idle but pretty good vacuum and throttle response.
