On that engine, unless you are getting it real cheap, there wouldn't be a huge benefit. Bump the compression up to 13:1, drop in a huge cam, and you might see something worth the hassle of converting to E85.

Many guys on LS sites are running 11:1 - 12:1 compression with turbos. They are getting 800-1400 hp on E85. That makes it worth using.
