Here's some evidence that the idea of cylinder wall lubrication via rod squirters isn't so new - the rods on a 1958 Rambler V8 had squirters in the parting line of the rod bearing caps that each lubricated the opposite cylinder on the opposing bank:

And John Erb of KB Pistons makes a sensible statement here when he suggests that OE piston skirts can catch major thrust face oil as they drop beneath the cylinder bore - leaving the curious to wonder what happens with shortened skirts such as the Wiseco pistons - and leading me toward the rationale for drilling the 3sx rods:

It's incredible how much we can learn with curiosity and an open mind. I would never have thought to check if a piston skirt dropped below a cylinder bore or realized that it did so to pick up lubricating oil for the thrust face.
