I just saw this "Ford Mexican 302 Block" on Ebay: http://cgi.ebay.com/ebaymotors/ws/eB...K%3AMEBWA%3AIT

Now what are the advantages of these, just the better wear-qualities of high-nickel content blocks, correct? Now 2nd and main question, what years and models of Fords got these? That'd sure be nice if my '72 Econoline has one
