Cast iron vs. Nodular iron third member? At what power level is a nodular iron third member necessary? I have a cast iron third member in my 9-inch right now. I'll only be making about 450 rwhp on motor, so the current rearend setup should be plenty. However, I will also put 300 hp worth of spray through it. My car's 3600 pounds and it's a six-speed. Should I consider upgrading to a nodular third member?
