Well yes and no...do you plan to do a lower pelley? If yes i would stick with the larger upper pulley so you have more belt rap and put a 8lb pulley on the bottom to make 14 to 15 pounds of boost which is about as much as you want on stock block and eaton....if i had to do it over again i would just throw a whipple twin screw on and be done
