Re: One oil pump modification now on file

Some years back, member PackardV8 discovered an important feature in the SBC oil pump body that was lacking in the Packard unit - a cast channel that provided a bit of oil to lubrictae the driving shaft.
Yet, I was never quite sure how I would go about carving a similar channel in the Packard pump body without possibly creating more problems.
Later, I decided it would be simpler and better to drill a small hole from the output passage of the pump to the driving shaft bore, but - again - I wasn't quite sure how to accomplish that (trajectory, diameters, etc.).
Ross, I think your approach - requiring nothing more than a vise, an electric drill, and some bits - is exactly what's needed. It seems very much in the spirit of what the factory might have recommended as a field fix (if only they had more time).
