I was hoping to see a Vega piston with iron clad skirts. I found a couple of skirts in my oil pan but that was due to abuse when auto crossing the car back in the day. A steel sleeved block and "normal" pistons made more power and was much more durable.

twas the lack of your ka-ossillator (G) see how it all blended together this time....the pistons didn't gouge the cylinder walls of the video. Teflon-ossillator 'music' ring-groovy

Interesting subject, but it might have been nice to spend a bit of time discussing why each design was made the way it was, and what each successive generation achieved and sacrificed with the changes that were made. As an example, those pistons with the short skirts allow for light weight, and large stroke/bore combinations, but they are less stable in the bore, and will not last as long as a taller skirted piston will. Not an issue in a NASCAR engine, but contemporary motorcycle engine designs use this feature, and they don't last like the older engines did! And also the thinner rings reduce friction while at the same time sacrificing longevity and are less robust than older designs...I've heard manufactures went that way for mileage and emission concerns, not because it was better for the engine parse.

What are the rings called that come up to the top of the piston? Kind of like an L shape ring.

+GREG GERHARDT Perhaps "Ridge Dodger" is what you are thinking of, designed to be fitted in worn cylinders and not interfere with the lip at the top of the cylinder :-)
