Instead of mucking the head thread, maybe experienced E85 guys can explain what's needed to convert. New pickup in tank, complete larger fuel line tank to carb, electric fuel pump, can I modify my 830 hp,? Does it burn cleaner, or is it corrosive? Will E85 have that nice race gas smell? What if E85 dissappears? In MI., some stations don't sell it as in the past. Ethan and others seem to have some 1st hand experience on this conversion.
