The engine had a flex fan on it and several of us kept getting cut on it. This thing was SHARP! Our cousin Chris came over and we changed the fan to an electric fan, which worked out fine since we didn't have a shroud anyway. We also changed out the header gaskets to cut down on the exhaust leakage. The driver's side collector is still leaking a bit because it is a little warped and won't seal up very well. On down the line we'll probably have to get new headers.
