I am stuck about which I should get. I have heard that an aluminum will rev quicker but they are pretty pricey to not get any *real* performance from. Which would you pick? These are the choices:
-Aluminum from JD's (no idea what kind) $359.00
-Steel from JD's (again, no idea what kind) $229.00
-Ford billet $219.95
-Ford cast iron $89.95
-Aluminum from JD's (no idea what kind) $359.00
-Steel from JD's (again, no idea what kind) $229.00
-Ford billet $219.95
-Ford cast iron $89.95
