What's wrong with this picture?

a full groove gives the rod bearings full time oiling, good for high rpm. 1 and 5 only feed on rod. the clevite 340 set is fully grooved except #3, so I machine it to 3/4 groove. 2 and 4 on a small block feed a rocker shaft. I think King and federal mogul hp had 340 sets with all 5 being 3/4 groove = the hot setup
