Cliff,

I understand your calculation and logic. Interestingly, when stock (with Marc's chip), 6th gear cruise (say 70-75) on 80-85 degree day (it's been awhile...) coolant temp would stabilize around 211-213. In 5th gear it would drop to 203-205 probably due to increased coolant flow. With one 1/8" hole coolant temp would maintain, if I remember correct, around 197-198 regardless of 5th or 6th gear - just my experience.
When I dropped in my 380 coolant temp went up a bit across the board. Also, after two blown OEM radiators I opted for non-plastic tank radiator and while at it figured I would try dual core/extra fin area option.
