so i have a 360 out of a truck,decided to put it in 68 dart,changed out the oil pan today and found this in the bottom of the pan,motor runs good with know noise,very clean inside and has been built in the past,sounds like a good rv cam,plus all the rods have been stamped,any idea what these bits are,i know the yellowish one is a rock,pieces are very flexible very soft grey in color
