Working on 67 Camaro with 6.0 lq9, 4l80E and vintage air. The motor has some mods, should be around 450hp at the wheels. I have the Griffin ls radiator with there dual fans. After reading more about them I realized the fans are only rated at 870cfm each. The car is not on the road yet so i really don't know if this will be enough to cool it or not?
