That is probably true, but only if using the block in a 21 stud application and they are drilled out. In the case of the typical 24 stud usage, the cast bosses would be below the deck, but not used. Therefore, we can "hopefully" bore all the way to 3 7/16 and still have decent cylinder wall thickness. I'd love to go to 3 1/2", but this starts to make head gasket sealing an issue.
Hmmmm . . . maybe I'll think about high quality 3/8" 'step studs' and go to 3 1/2". I'll have to look into that!
