Howard 500, very cool.
I actually googled largest reciprocating engine, as I knew there was something by Lycoming, but I couldn't remember what the displacement was, and it was the Lycoming R-7755. It never was successful, as by that time the development of radials had reached it's zenith, and hair dryers, er, jet engines took over.
