I think thats the same block deminsions for all 428's, smaller bore and longer stroke than a 427.
The big deal with the 427 was the larger bore allowed for larger valves and better flowing heads. Racer trick "back in the day" was to use 427 heads on a 428, BUT you still had to use the smaller 2.02 (or so) max valve size. Same problem with this new small block 427W, your limited on valve size. Even with the 427 FE and it's big bore the top of the cylinder bore had to have a "notch" in it for max valve size clearance.
