Yea that was another idea. or getting better quality fans with a higher cfm rating. These match what the factory rated for the z06 corvette, which is what the radiator came out of. So as long as my shroud it 3/4 as good as the stock plastic one I should be ok since the z06 had the more hopped up motor making a little more power then my little ls7 cammed 4.8 with an big boy intake and throttle body.
