How coincidental. I am experiencing the same scenerio on my Roush 427. I upped the thermostat to 195F with little to no effect. I am going to verify my temp gauage tonight. I assume our radiators are to big?? You would think the thermostat would close at 195F, I can beleive the water pump by-pass allows that much coolant around? I thought that was the purpose of a thermostat to maintain a minimuim temp. Around town it is fine but on the freeway to cool. Anything below 165F results in substantial piston to cylinder wall wear.
