Fast question for the ZL-1 block experts here. I had been
told numerous times that the original ZL-1 blocks were actually
a bad block design ( weak bulkheads ) and that these blocks
actually weeped oil right through the castings. Is there
any validity to this? Some of the members on the NCRS.org
site actually raced these engines back in the day and the
general feeling I got was that the new ZL-1 blocks were so
superior to the originals, that some members would give an
old ZL-1 block away in order to get one of the new ones.
