Casting numbers are on the valvetrain side of the head. Pull a valve cover, they should be 6 - 7 digits.
BTW, a big block will have more than enough torque to do anything you want, even with a much smaller cam. Lumpy cams are a ***** to drive in the cold weather and tend to foul spark plugs if just used for cruising. A cam in the 230-236 range will have plenty of chop but still be very streetable.
