How much validity is there to the idea that it is detrimental to a motor's longevity to have the pin intersect the oil ring in any way?

Chris,
If the wrist pin intersects the oil ring, it allows for more blow-by of the combustion gases into the crankcase. This can lead to the unburned fuel that gets into the crankcase to dilute the oil, making it thinner and eroding the lubricating properties of the oil. Of course, this will lead to premature bearing (usually main bearing) failure.
If you built such a motor, you'd just have to monitor and change the oil more frequently.

Oil burning. The motor will burn oil.

I feel if you have to go to those extremes to the point where the pin intrudes on the oil rings to gain Cubic Inches out of a small block and need the long stroke......... guess what I'm going to say..... ITS BIG BLOCK TIME ..... 500 inches. OH NOW YOUR SPEAKING MY LANGUAGE.
