anyone have a zf6 with 3.55 or 3.31?

my 6.4 has 3.73 ratio and I've been thinking about switching them out. the first three gears run out quick when i get on it and also its sitting at about 2000 rpm at 70-75, the gears are great for towing but it would be nice to have a little lower rpm on the highway. Does anyone have the zf6 with 3.55 or 3.31, how do you like it, how does it tow, how is the daily driving around town, on the track? Thank you for any input guys it is appreciated

I THINK, not 10% sure, that the ZF6 trucks only came with 3.73 or higher gears.
This site: Ford Vehicle PDF Brochures has a PDF of the sales brochures back to 08 available and I looked in there and I did not see anything mentioned as to rear axle ratio other than the Tow Boss package having 4.30s. I will search around and see what I can find...
Also, my auto has 3.73s


EDIT: Found a listing of what appears to be all optional rear ratios. The 3.73 open diff was the standard equipment with limited slip available as an option in 3.55, 3.73, 4.10, and 4.30 I do not know the accuracy of this information though as I cannot remember hearing of anyone with 3.55s in anything stock before 2011

My window sticker says 3.55 rear end but there is no way. 70-75 I'm close to 2000rpms also so not sure why my sticker says 3.55 when I have a 3.73

I think 3.55s were offered in 09+, not sure if it was behind the ZF6 tho.
