I only assumed thats when they were fitted. The 18V engine was in the
Marina long before it was fitted to the MGB, perhaps ALL 'B' series were
so 'shimmed'. I still have to find a reason, and am following it up.
Marina 18V made from April 1971, MGB 1975; Paul Hunt did say that one of
his sources told owners to retro-fit them to earlier engines as well.
