E85 carbed 6.1

I was going to run e85 with a supercharger, but I decided to scale my build back within my means. From everything I know about e85, I would NOT use it unless I needed the additional anti-detonation advantages it offers. Like Clint- switching because it's e85 r race fuel. And I'd only do that if the savings were significant (which they are vs race fuel). Is e85 more than 30% cheaper than 93 for you?

A lot of fuel pumps and lines don't like e85, FYI...
