E85 fuel system requirements

I have searched many different threads concerning E85 fuel use in my 00' modded WS6 with no avail, either many pages of in depth techno jargin or much flame throwing on this subject.E85 is readily available in my area and would like to run in my car that sees limited street/dragstrip use,looking for some useful info on what i need to do as far as tune,sensors and fuel pump if anything at all.Fuel injectors are more than adequate, 11-1 + compression, big cam,frost tune,everything matched.Any info as to switching from E85 to regular fuel use,like the newer flex fuel vehicles are capable of, if feasible in my vehicle, and compatible fuel pump,seals that i may need to change.
