What should I do gearing wise to get the temps down? try 60 or 58 with a 12? I know there are the gearing charts but those arent helping any right now. Thanks for any help you guys can give me.
Where are you topping out at down the longest straight? After talking with the Late Big Jim, one of the premier motor guys of his time, he advised me to always start my gearing to top out towards the end of the longest straight, then adjust it from there. Based on his suggestions, I have never overheated a motor since. Give it a try (assuming all else is fine with the vehicle)

The manufacturer probably had a card or something stating a safe temp, but in general about 150 - 170 could be considered safe. Also keep in mind that when you actually temp, your motor was probably hotter at some point too, so kind of factor that in.
