You are trying to manually control the timing, fuel ratios, O2 sensors, knock sensors etc.. running temps that normally are controlled by a sophisticated computer making 1000's of adjustments all the time. This is not a carbureted 318. A 6.4 with 11.5:1 CR ? who knows what else done to the engine and an aftermarket EFI/computer. Who knows what "normal" is on that setup. This engines cooling system is 2000's technology.
Did you know that The stealth bomber can't fly without a computer ? Modern engines are designed to run at much higher temps then the "old days" Going through the desert with no coolant only water. No recovery system only water loss every time it got hot. A canvas bag full of water hanging in front of the radiator to cool/humidify the air before it passed through an overloaded radiator.
And all because " I don't like it when it is "hot" ?. Hot is relative. Hot on a non pressurized cooling system with water is a lot lower than a 16+ pressurized system with the proper mix of modern coolant. A computer controlling everything and a coolant recovery system so you never need to top off the radiator. That is today. Modern engine/computer technology with a 1960's cooling system, just doesn't get it. Modern engines/cooling systems are designed to operate well over 212 ° What Pressure Radiator Cap Rating Should I Use? The Functions of a Radiator Fan
