Q: This engine was displayed at this year’s Reno Air Races. There was no information posted at the display, nothing to indicate who owned it, identification/designation, what it was or its intended use. It looked like three P&W R-4360 engines put together.

Any thoughts, comments, or information on this engine would be appreciated.
