Sloppy timing chain

I have been working my way through the drive train of my 74 Euro Pantera and have resolved a lot of issues.  In the 1990's I think the engine was built to a high end street racer spec and then driven like it was stolen.  There are a lot of really nice parts and workmanship inside the engine.  Sometimes it is hard for me to tell which parts are still good and which parts are trashed.  While working on my other GTS clone Pantera I noticed how tight the brand new timing chain was.  Then it dawned on me how sloppy the timing chain in Euro Pantera was.  There has been a troubling sound at the front of Euro Pantera's engine for a long time that has grown worse.  This weekend I replaced the timing chain in the Euro car's engine and the troubling sound is gone and the engine seems to be running better and is certainly quieter at the front.  Here is a short video of the slop in the chain.
