Did anyone ever build an engine with the rings

Did anyone ever build an engine with the rings embedded in the cylinder instead of the piston?

It would have to be a pretty short stroke but I could see some advantages to doing this like the block never wearing out. pistons would need to be heavier and probably sleeved.

I doubt it. What would the advantage be besides not wearing out the block? The pistons would need to have a steel sleeve on the outside making them so heavy I think the internals would need to be beefed up. With all the extra rotating mass, I wouldn't expect any type of performance out of it, let alone if it will actually run. If it did run, it probably wouldn't be for long.
