93 octane.... that is an option if you want to keep 10:1. I build my engines to run 87 octane. I think with AFR's and 9.5:1 you could run 87 octane, get decent milage, and have plenty of power. You could even run 87 octane on a 10:1 engine, but you have to build it just right, tune it to the gnat's ***, and hope the car gods are smiling on you.
