Hey John , just a little over 2 wweeks ago, I installed a 4:10/11 3rd member in my '54 3800 panel. I was driving on the frontage roads at a speed of 50mph, now that I've changed the rearend she will top in at 72mph, and that's with 7.50x17 12ply tires and the old 3 speed with the granny gear. I filled up on fuel last night and in the next day or so should fill up again and when I do, I'll tell you what kind of mileage I get.
