I hope you meant 11.4:1, and not 14:1. 11.4:1 you will probably have to run 110, 10.5:1 is getting to the upper limits of 93 safely, I suppose if you retard the timing you could run it, but thats taking a step back. If its 14:1, your f***ed. Something like a 14:1 motor needs to be run on no less than 116 race fuel.
