I had that happen on a440 in a 73 Town & Country I once owned,and it had about that many miles on it. But, I thought plastic coated timing gears didn't become an industry wide thing till 68. I remember my dad's old Catalina having to be fixed by the dealership, but I'm not sure right off of the top of my head when Chrysler changed to these. I would assume post-68 though.
