I am seeing these mills pop up more and more at our local track and I'm noticing how smooth and linear the power band is of these things, there is not dead spot. I have only ran o.s. motors and I currently run o.s. motors in my 8 2.0 and 8t 2.0 but with what I'm seeing I am enticed to get me one of these, with its smooth powerband and increased fuel mileage and the value makes it almost irresistable.
