I have never seen a cam gear wore so badly. It is no wonder the s.o.b jumped time. It was over 90 degrees out of time. This came out of the 351W in my 84 F-150 4wd that I just bought. This is the original gear that came in the truck. Anyway, I just had to post this pic. And to say don't buy phenolic gears just because they are quiet. LOL.
