Being as the picture shows it all polished up, and I'd assume you're both located down south, I wonder if it's not the same engine as in this post:

If I'm not mistaken, that polished engine has been around (and on) the block a couple times before...I think I've got a bunch of pictures of it on one of the computers here...not sure of the legality of the crest being put on there and sold if indeed it was done in '97...
