Its got 3:54 open diff.
It used to get good mileage, before the exhaust was put on! lol. That damn flowmaster it costing me $$. Have the rear cat taken off and replaced with 3" tubing to the SI/DO Flowmaster 40's series, 2 1/2 inch pipes straight out the back with Gibson 3 1/2 inch tips.
Before the exhaust, I would get around 15 mostly highway. On a trip down to Grand Rapids, about 400 miles round trip, I averaged 16.5-17. Best I've ever got was little over 17. Since the exhaust and me being harder on the truck now that I got used to it, I average right around 14. A couple times I got 12, but high 13's low 14's is what I've been seeing over the past couple months.
No real plans yet. Almost took the tranny out and rebuilt it because the sychro's are weak. It still shifts good, I'll see how long I can go. More than likely I can easily make it to next summer. Hopefully by then I'll be owning a 2004-2008 F-150, and I can do some better mods on that like a nice suspension lift.
