If you do that your life will be miserable. My buddy has a car like that and it's such a hassle/expense to drive it he doesn't drive it anymore, he can't enjoy it and now talks about selling it. Stick with pump gas. This isn't the old days. You can make all the power you want on pump gas with no downside.
I agree, you will have more fun and drive it a lot more often on pump gas. My Duster(wedge motor) runs on 92 octane, drive it almost every day and runs mid 10's at the track with highway gears. You'll make plenty of power either way.
Another option is E85, then you can run 13.5 compression at around $2.50 a gallon. Lots of guys in my area run it, but I will say it puts out a strange smell.
