Going to 4.10 gears will help get back the power and torque you'd lose with the 33" tires.

BTW, you don't need 7" of lift to clear 33" tires. With that much lift, you could run 35" tires, but you'd then need 4.56 gears. But I don't think I'd run 35" tires on a Dana 35 axle. Ford 8.8 would be nice, but it's a little narrow. You could solve that robem with either wheel spacers or with custom offset wheels.
