My 272+40 CEBY block is currently in the machine shop waiting for me to decide what bore size to go. Every thing I have researched indicates that up to 3.83 is not a problem, but an Aus. parts supplies who specializes in Y-blocks told me not to go over 292 because there is not enough meat to go any bigger. Are the Canadian/Aus blocks different to the U.S. cast ones? cheers Peter
