For anyone who has put in 3.73 or lower on thier falcon, was it worth it? I am thnking of 3.7 or 3.9 gears for my XR6 (EL), just wanted to know if it worked better on the quarter, and how much more it revs to on the hgihway. Mine sits at 2100rpm in 5th. I don't do many highways kays, only up to melbourne then and when. Although we would all love better fuel economy, it's not that much of an issue to me. I would use more fuel to go faster anyday!
