Get the shipping weight for the 1968 Mustang ( with the heaviest engine ) , then get the shipping weight classification sheet for the year of the 352 engine you want to run . Some times the GT engine is factored differently than the Super Stock engine factor . Once you figure out the engines HP factor then the natural class is the Shipping weight of the car divided by the GT HP engine factor . This gets you your natural class which you can adjust to the bottom of the class . Minimum weight for that class across the scales requires you add an additional 170 lbs. You are allowed to go up one class and down one class , but that's another discussion .
