Yup or old timing chain plastic.
I took an oil pickup off one upon on a rebuild and it sounded like a baby rattle.
Your oil pressure is fine for a stock motor, it starts ticking consistantly it time for repair work.
My dad a 66 fury with a 225 he bought new, at 180K the oil light would come on at a stop sign, lighly blip the throttle the light would go off.
It never blew up.
