The timing system on my 289 has a cam gear / sprocket with plastic / nylon teeth . As a typical teenager of the time ., I had flogged it many times . The system was so worn I removed the chain before I removed the gears / sprockets . Had to go down to the parts house and purchase a puller to remove the sprocket / gear from the cam .
So much slack on the slack side of the chain , it had been rubbing on the front cover .

I had a 289 in a 1965 Mustang and it had a timing chain and the chain had a very simple path, from the crankshaft up to the
cam shaft. The engine had push rods. I rebuilt the 289 in my Mustang at age 17 and learned a lot about engines.
Today's engines with a timing chain have a much more complex path for the chain with over head cams, idlers. [/quote]
