Philbilly,


You can start with 36-37 timing & if you run real good gas 39-40 ..? You need to try it at track .. It depends on headers,cam timing, jetting, valve lash, trans/gears , etc .. Go to a test n tune & make two runs where it is , then advance it 2-3 degrees and see what happens ? Then put back to 34-35 degrees and see what happens, don't change anything else !!! You will then have a baseline for that kind of weather, I think you will PU when you move timing ahead ... Let us know what you find out ? One change at a time ... LOL ....
