I'd even lower that to 9.3:1 with the great state of california (lower case on purpose) garbage fuel they call gas. Lots of engines built around here for comparison, and anything higher than 9.5 gets the can of marbles going under the hood regardless of timing tweaks and carb jetting when the temps and fuel take a turn for the worse. Bart stuck to 9.1:1 with his 421 build and he won't be hurting for horsepower.
