Swapping gears will be more trouble than it's worth. And you need the 4.10's for pulling anyway. A 350/Crew is basically a long brick with a shorter brick on top. That 360 will only push so much air economically. The best shot at better mileage will be swapping in an OD tranny. The A518 has a .69 OD, which means that 2500 RPM in direct will be 1725 RPM in OD.
