Changing 2018 from 3.31 to 3.73

You really don't need a 3.73. I've got the HD tow package and wish mine had the 3.55 because at 80 mph you are turning over 2000 rpm which kills fuel mileage.

I asked my local Harley Davidson dealer, about converting my 2800mi, 03(100th anniversary) FXD, from carb to fuel injection. They said it would be cheaper to trade it in on a newer model, already with fuel injection. You Expedition is not meant/built/setup for towing. Get one or something that is.
