[427Bullitt]

Hey guys, n00b here and I'm building a 427 and was wonder what the highest compression ration you can have and still run on 93 octane. I'm trying to get all the horsepower I can out of the motor, but don't want to set the compression too high and mess with the timing so much that i defeats the purpose of it being a high comp. motor. Any input would be appreciated, about the fuel and what parts have worked best for hp gains.
