Overheating 360 new engine

You are going backwards. That shroud is no good. Pray you don’t have an electrical issue where you lose power to, or have to shut off power to those fans to conserve battery power. You will never get it to run cooler with that setup. Talk about the air packing up and not flowing though......good lord. I notice you never positively identified what water pump you are running. Six vane, eight vane, plate on the impeller?
