What are running as fuel? VP 16 will help you make the power and avoid any detonation.
That would be more octane that I need.I have not gone over an effective CR of 15: and will stay there untill I get it very happy.I'm getting very close with the carbs and sill experimenting with timing.Last 2 times out the top end charge is not there
When the cooler air comes in the fall I will check plugs after every run instead of just reading the racepak. I will also try different heat ranges.
I have the start and cruise lookin good,now need to work on WOT.
Question........will the plugs read the same at the top of 2nd just into high gear as they will at the stripe? I go over the stripe at 64/6500 rpm
