You will find most HD blocks have the crow's feet webbing as your CX. Also more girth underneath the crank support area as well. The CX blocks just had thicker walls and are rumored to be race blocks as well. I can't confirm the race block thing but they are thick walled for sure. Sounds like you scored a nice one! G.
