Woodman, another thing you can do is try looking for an 02 mountaineer 4.6 they came with an aluminum block... just putting it out there in case you didn't already know.
Thank you, the one I'm looking at buying right now is an 03 Mountaineer block. It's $300, I may have said Explorer above but yeah, they're both the same.
