Overheats, not hot. Cold to peg gauge in 5 min. New pump, stat, sensor. Ifr <160
What is your question?
Goes from ambient (85) to peg gauge (230+) in < 5 min idling. Infrared thermometer reads under 160 on heads (header manifolds barely 210). Replaced pump, stat, hoses, belts and temp switch (85,000 mi) for small leak at pump rotor seal which precipitated overheating trouble. Engine shuts off when guage hits 235. No other apparent problems, no trouble codes logged. Runs perfect otherwise. Repeatable over and over. All stock. Private use 1 driver vehicle. Computer issue? Help appreciated.

Radiator restriction.. Poor air flow through radiator... (Fan issue)... Air in cooling system... No inherent cooling system problems that I have found in any of the Vortex engines... Only other thing I can suggest is install manual gauge for the most accurate testing..... Good luck!
Temps are as shown, engine is 4.8 V8.
