If you have questions specifically for Woody, you should just call them. He and his wife Nicole are very helpful.
IMO, a 460W is really not necessary, especially if you have FI. A good 4 bolt main block with a rotating assembly to match in a 427 would be more than enough for it. Turn up the boost and make whatever the block and bottom end can handle (probably 1K+).
