With only 114K, its unlikely that the engine was rebuilt, unless it suffered a
catastrophic failure.  The factory timing specs were often a bit conservative,
and that might explain why it does not ping.  Also, you may not be advanced all
the way to the recommended 8 degrees.  Most pinging problems in these old cars
are more likely to be related to deposits due to too much city driving and not
enough high speed.

When unleaded gas was phased out, the 68 model year was long done with its
warranty.
