Trenches in high loaded areas, ie top or bottom are generally to be avoided.
The Seven with its curious lube system is different. The oil spray is everywhere and I suspect quite a lot is slammed into the drillings on the upstroke. At the top of stroke oil would exit and serve to briefly vent oil and air from the main entries on the crank.
Did the 3brg shell cars retain the rod drillings? Was the shell trenched?
(Incidentally blocking the holes did not seem to reduce oil consumption on my car)
