Help with VIN...

Ran a VIN on a car I have the opportunity to purchase, it decodes as a Barracuda, Special, 2dr htp, 340 240hp 4bbl, 1973, made in Newark DE...

Anybody know what the "Special" stands for???? And just for the hell of it what would/could it be worth as a rough but running project. It currently has a 318 in it but the (supposedly) original 340, condition unknown other then there are no holes in the block, comes with it. I haven't had a chance to look at the fender tag yet.

Thanks....Dave
