I am getting ready to transplant a motor in my 61 wagon, it currently has a 260 that the previous owner put in that needs rebuilding and I have no idea about the trans. I put a 302-C4 in my 61 Ranchero without too much hassle but I want to get some more mileage and reliability (plus do something different I hope) and am thinking about finding a 4.6 4R100 and putting it in the wagon. Has anyone seen this, heard of this or anything? I think it would be a neat swap and since those motor trans combo's are everywhere (like the old 5.0 AOD) it should be pretty easy to get the components. Any thoughts?
