I was at my uncle's house yesterday looking for a set of seats for my Nova. We found some in an old barn, and my uncle spotted an intake. I got it out and it was an edelbrock streetmaster 440 intake. I have never seen one of these so I assume it is an older part, from the 70s sometime? It is a single plane design. It is in great condition and all it needs is a good cleaning. Any ideas what it would be worth? I forgot it at his house, otherwise I would have posted some pictures of it. Thanks.
