On my Pontiac 250 engine, the oil spurting hole there is facing the passenger side of the engine, which is the cam side of your engine. From what I read, this was to help lubricate the cam, and in my engine's case the distributor gear drive and fuel pump lobe.


That would make a lot of sense actually to lube the cam lobes.

And the bottom of the rod caps were ground for balancing. There's nothing indicating on them.
