I'm trying to clean out my basement, and have a set of factory exhaust manifolds and the original two barrel intake of a 69 RS 350 taking up space. Is it worth the effort to try to sell them or should I just push them further into the corner?

 

You'll probably get more for the exhaust manifolds than the 2bbl intake. Check out ebay for similar items (check part numbers) and you might be surprised at what they're worth.

 

One man's garbage is another man's gold. You should find out if the numbers on both are from the correct castings. I'd do it EBAY
