strange timing change discovery on my '68 2000

["Cohen, David M" <D.Cohen@hp.com>]

Hi all,
  I have a very strange problem.  When the motor is cold, the top timing
chain is tight on all the rotation except when the #1 cam lobe is in the
2 o'clock position.  At that point the chain loses enough tension to
pull the chain all the way into the L-bracket.  Once the cam passes this
position there is tension on the chain again. Any ideas what the problem
is or is this normal?
