Google is your friend. I just did a quick Google search and found a site that has 3 of those engines listed not too terribly far from that area.
Yesterdays Tractors doesn't allow me to post the real URL's to the site where these engines were listed, just remove the dashes from tractor-parts-asap to get the real URL's.
This one in Iowa is the closest to you of the three that I found after a quick Google search:https://www.tractor-parts-asap.com/Ford-engine-p/en-5083.htm
These two in Wisconsin and Minnesota are a little farther north for you:https://www.tractor-parts-asap.com/Ford-engine-p/en-1982.htmhttps://www.tractor-parts-asap.com/Ford-engine-p/en-2097.htm
