with those 3 options i would have to consider what the rest of the drivetrain will consist of, a tunnelram wont do much good on a otherways stock motor/drivetrain, i know bob knows this aswell and im sure he will do the right thing in the end, if the rest of the car gets built for it, #3 sure is the way to go if the rest of the car does everything to be stock looking option #1 and #2 would work for anything else
