CHP sells one. I may purchase one, they are inexpensive and will add a little extra insurance. It seems that stock blocks are limited to the 4.000 stroke. If you go to the 4.1 or the 4.170 to get to the magical 427w, most guys suggest to go with the Dart or World block. I don't think there will be a huge HP difference between a 408w and 427w, using the same basic components.
