Today a google search on E85 turns up on 515,000 hits. The first one is linked below.

As I said above, converting an injected engine appears to be far simpler than converting a carbureted engine for 85% ethanol.

Using E10 (gasohol) in a vintage engine may mean no more than making sure the ethanol doesn't dissolve fuel lines, float varnish, gaskets and o-rings. There is chance that the ethanol content may loosen crud in tanks and lines, but modern gasolines often have detergents that should have already cleaned the lines. If gasohol does loosen crud the fuel filter will catch most of it.

Running E85 through a carburetor is more difficult. Takes effective manifold heat, larger jets (27% in diameter according to some research reports I found on the internet yesterday), and provisions for some other fuel or warming the E85 for cold starts. Also those documented projects I've found mention working at better fuel tank filler fire flashback prevention.

EPA and CARB are against E85 conversions not done by factories and require a regimen of tests impractical for individuals.
