It doesn't read like a Yenko Conversion to me. By the looks of that tag, it's probably just the #1 Convertible Conversion that ended up with an over-the-counter Yenko Aluminum block/engine. That being the case, it's not priced terribly expensive and I would think that a fellow might be able to buy that car reasonably, harvest that Alloy Rat outa there and replace it with a 400 Pontiac and possibly re-coup most of your money back.
