If you are doing this just for better milage it may not be a good return on your $$$ unless you drive a lot. You look at what your present mpg verses what improvement will be gained...then look at total cost to make the engine mods. I will be spending $$$ to have my 402 rebuilt this winter plus I will likely install a Gear Vendor unit. I realize I will never see a positive return on my expenses but I am doing it so I can have fun when I do go out for a drive. I am not sure any of our V8's get really good mpg? I might be wrong. Sounds like you have a nice project and your truck will be fun (more fun) to drive once you get your upgrades completed. Good Luck.
