Overheating 360 new engine

OP, if your eyes haven’t glazed over, spend less time measuring various cylinder temps, micro managing temperature across the engine etc etc. Recipe for descending into madness. Run an 8 vane water pump with a plate, if you have a 6 vane pump yank it and toss it. Gotta move the coolant! Gates and many others offer them, OEM style is all you need. Add a High flow thermostat, it’s temp is irrelevant and depending on the shroud you have if it is flat with fans mounted then cut openings on any of the larger flat area expanses to allow air to flow through vs packing up. Air-flow vs air -packing. Cut some heavy rubber flaps and screw/rivet them on the top side of any opening so at a stop they will lay flat, allowing the fans to do their job, and at speed the flaps blow open allowing airflow.
