Hello Guys,
I haven’t posted in a long while, but to answer the original posters question with careful shopping last month (October 2010) I found on craigslist (SF Bay Area) a FoMoCo casted C6AE-9245-A Weber manifold for $500.00 I believe this and the C6FE/GT40 manifold are exactly the same.

I think the add is now gone, but I attached a pdf scan of the Craig’s List posting from my files.
Anyway here are a few pics of the manifold on my kitchen counter.
Cheers,
