You will love the conversion, I put a 6.5 in my old 71 two wheel drive truck and it always got over 20mpg and on a 300 mile trip got over 35mpg. And don't worry about power, if you ever get to that point a turbo and upping the fuel will do the trick. My truck was putting out around 500 ft/lbs of torque on a dino. I don't know about a 4wd but on my 2wd the only thing I had to modify was the engine mounts on the truck. I had to cut the top of them and put a flat piece of metal where they were rounded so the manifolds would clear, but it is still very close. Hood clearance was also a thing for me, but with a body lift like yours has it shouldn't be a big deal. And for the return line I just soldered in a nipple on the tank. And the 700 will hold fine, I had one behind mine for a long time. But after you turn it up if you ever do, it NEEDS to be beefed up. I went through 5 after I started putting out as much power as I did. Just FYI.
