I have since put 17s on back (had to get speedo calibrator to keep from hitting top speed govenor before end of the 1/4 mile), 180 t-stat and removed to clutch fan. I am going to MIR this weekend (weather permitting) and am expecting to it run uncorrected 13.9s. With your 3.92 gears, you should be able to do it without the 17s.
I have the single cab Express, and was considering 17s , very interested in knowing how well you do. My truck sits high and I don't want it to look bad may consider dropping it, or at least a leveling since the rear end is pitched up quite a bit. But your talking 6 tenths just by changing rims , that's huge, and I'm not wild about the aluminum look on my black truck. You can't go wrong with black and chrome anyway.
