Here's a picture of the wrist pin that failed in my motor causing a second rebuild. These are the tapered wrist pins that come with gt pro/ross pistons and are made by western wrist pin. You can see from the pic, it looks like the material is brittle and didn't shear. Instead - it looks like it snapped. I also had to get a new set of rods because the machine shop gt pro used to use - bensons - completely ruined my connecting rods. Where the bearings seat as well as the mating surface were damaged beyond repair by bensons.
