SBC 327 2 speed glide question

I usually hate questions like this, but my research hasn't turned much up for me, so I'm forced to ask it.

I'm aquiring a SB 327 engine and a 2speed transmission. It's coming in a project I bought. I don't think I want to keep it, but have no idea what it is worth. It's pretty much a stock motor, has an aftermarket manifold on it, but I have a cast stock 4bbl manifold from a 350 that would probably be the same? I'm not sure yet if the tranny housing is aluminum or cast. The guy is sending me the numbers for the tranny and engine soon.

I know these things are pretty desireable (thanks to milner). Wondering what fair market value for this engine and tranny would be. Anybody have any ideas?

Thanks.
