My 460 ran hot as well. I did the usual....cap pressure, bleeding. water wetter...etc with little success. I finally got rid of the march pully set and went with a much smaller alternater and pump pully. Also changed to a high flow pump that wont cavitate, added the original style pusher fans up front, and a 160 thermostat. Now I run 175-190 degrees no matter what or where I am. It sure made life alot easier, and spewing water everytime I stopped is a thing of the past. Also check timing and fuel...lean makes em run hot. I also wrapped the headers, and that helped too........John
