I am usually all about originality, having said that I think that engine is gorgeous. I would love to have it in the corner of my garage as a show piece and backup engine. I would not pay anywhere near what they are asking simply because I don't NEED it. It is probably worth it frankly, just not to me. If I needed a replacement engine I would have no concern about swapping it in and no longer being numbers matching.
By the way, I don't see a smog pump....does that mean its a high compression euro?
