Mark,
You can replace the original filter with a Motorcraft FL 300. It is short enough to fit between block & frame rail. How to remove the old one is another story; I elected to cut in half with a hacksaw blade, kinda crude & messy, but I didn't need to move the engine. Then again, you can go for the remote filter mount and
oil cooler. I don't think I need it with my 351.
Have fun!
