Standing dead, if it's "solid" and doesn't have 2" of fluffy punk-wood on the outside should be 9/10ths as heavy as "green".
I know that a standing dead red oak can be sawed out and will produce lumber of the same quality as living wood from the center portion. The moisture holds on in red oak like a toothache.
My guess: 4900-5000 pounds in a cord of it.
Thanx for the input. Unfortunately, it hasn't happened yet. The tree service I was getting the wood from had a broken-down truck to deal with today, so the tree still stands.
