Value of 426 Wedge block?

The HP stamp is interesting. I'm assuming that is a 426 street wedge block but I'm not an expert on them. I do have a 426 street wedge car but the original blocks are fairly rare. The ones I've seen had the smaller font HP but who knows, maybe the big font HP was also correct. I don't know what the block is worth, all depends on who wants it and how bad they want it. I'd want to know the bore size and see a sonic report before I offered any money on it. It isn't worth more than a few hundred to me but it might be worth more to someone else.
