There are factory cars that run the E-85 alcohol blend that run ~9:1.
The whole point to running alcohol is that it burns cooler and can handle higher compression ratios, thus more power... That said you can run it in a low compression engine - just won't make the power... I've had to run it in a ~10.3:1 engine when I blew up the main engine in my mod and had to run a "street stock" 355 that I had laying around...
