The rod with 2 oil holes puts them right in the middle of a very high stress point in the rod. VERY BAD! Mopar Performance has recomended against putting pin oil hols in this location on the rod for at least 40 years.
With a constant spray of cool oil, I seriously doubt the pin will be lacking oil without an oil hole. Most engines don't have piston oil squirters so aftermarket rod manufactures simple put pin oil holes in all thier rods.
