Stock 440 rebuild: direction of piston

The beveled edge on the big end of the rod always faces the crank. That keeps the bearing just a hair farther from the edge of the crank when installed. Does this make sense to you?

Look at the counter weight on the crank; see the bevel? your rods have a bevel on one side; they fit there. And the little hole in the bottom side of the rod squirts towards the cam.
