Amazing that the most powerful engine was made by Lycoming and not Wright or Pratt.
Imagine where big pistons would be by now if jets hadn't come along. Based on car development, I guess fuel consumption would be 30% of what it was and I dare say there would have been big improvements in weight and cooling drag, not to mention reliability. Maybe they would all have been two-stroke diesels? And as we complain about modern jets sounding like bland vacuum cleaners, I bet my 'alternative future' big pistons would sound like characterless sewing machines
