408/360 question

I have almost 12:1 and I run pump gas most of the time. The issue is, you spend all that money building the motor, you hate to hamstring it with pump gas. It is kind of nice to have the choice. I have been talking with Rob Mix about his E85 carbs. If interested, check out this site. http://www.e85carbs.com/ 105 octane out of the pump. And cheaper. It requires 30% more fuel, however. I have a Clay Smith high volume fuel pump and am going to run 10 AN from the tank to the pump. I already have 8 AN to the fuel rail. Gotta buy that carb! I live in a small town, but it five gas stations, four of which have E85.
