ByronRace: Just when you think you're King of the Road, along comes someone meaner and nastier! I look forward to checking out your impressive sounding machine sometime soon. Tim: Cooling for Big Blocks often seems to be a challenge. My beast's new engine initially had problems when I was caught in traffic. The solution was a custom radiator shroud. I also used my old 16" puller fan, went to Water Wetter, distilled water and just a couple of quarts of anti-freeze (no freezing problems with my car in the garage overnight). Hasn't come close to 100 degrees C. since.
