I agree that a 180 t-stat is needed, but it needs to be an accurate t-stat. I prefer Ford, but others here recently have been having alot of luck with Robertshaw t-stats. Avoid Stant t-stats at all costs, but you might want to buy one of there radiator caps (at least a 15 psi). As another gentleman here just discovered, a good sealing cap is crucial. Last, but not least, drain your cooling system and refill with straight water, no coolant. Under stock conditions, I would run 20% coolant, but recent studies I have seen confirm what I was taught working for Bill Elliott, which was to always run straight water in a high performance engine. Coolant retains heat, and with 4.10's and an 8" convertor (you better have an external tranny cooler!), I'm sure you run plenty hot! By October, flush your cooling system and refill with the 40/60 mix Jim described above, and leave it that way through the winter. next spring, do the water thing again. I have heard concerns about the water pump requiring some coolant for lubrication, but for 6 month periods, it shouldn't present a problem. If you are really concerned, and insist on having some coolant in your system, use no more than 10%.

Those things, when combined, will reduce your engines operating temperature.

Take care
