I doubt if you can make much of a dent by hand as the metal is too rough and coarse. First off, I would remove the alternator and use air tools if I where to try to polish it, but that is too much work for me, I buy a chrome case kit for 80 bucks and have the case halves swapped out. I painted my LT1 intake with POR 20 silver and covered the top with the chrome top plate from Street and Performance, Street and Performance also hand polished my water pump and throttle body.
