Here are some night shots of the belly pan I took tonight. I also included a couple pics of the removable grill block. It isn't the prettiest with the well nuts but it has worked out fine. I have a full block one and the one that has the cutouts for my Hella 4000 compacts. I would like to make a clear block so the Hella's can shine through it.
WE3ZS, Thanks! I would love the ability to lower the Excursion with air bags. I remember the Lincoln Mark VIII's air suspension lowering at speed. The belly pan is even with air dam. I would like a more solid air dam to close the front off some more.
I did get 3.55's installed because the dealership re-installed the stock 3.73's incorrectly when they fixed the pinion leak. I got the 3.55's off of a forum for CHEAP. I sounded like I had super swamper's in the rear for tires when the rear took a crap. The 3.55's dropped rpm's by 200. For tuning, I have looked into ficmrepair.com for an ecotune. They are the "go to" for the 6.0. It costs $150 and everyone claims a 1-2mpg increase.
WE3ZS, my friend has a stock '05 F150 5.4l that gets 13-14mpg. Your lifted EX is getting pretty much his mileage in a way bigger vehicle. I am going to go make fun of him now.
