I seem to recall an overheating post where the coolant was moving too fast through the rad to actually cool the coolant due to an oversized or many blade water pump.
Could too much pump pressure cause the stat spring to stay open? Just something to possibly consider.

I remember reading somewhere that with too much flow, the coolant does not have enough time in the rad to cool down. I think there is a thread on this in forbbodies only.
