Well, not trying to be a smart-alleck, but your sample size of 2 really doesn't represent the thousands and thousands of engines out there.
You would be shocked to see the amount of engines that not only leave my shop, but every other hipo engine builder's shop with the rings up in the wrist pin.
A 347 Ford is one of the worst situations with compression height...they are sitting at a 1.090" height, with the
oil rings right up in there. I know of one particular guy with over 100k miles on his 347....no oil consumption.
The wrist pin intersection deal is just something that gets passed around the forums and it all stems back to a single faulty piston design from decades ago from Coast High Performance/Probe pistons.
