1924 McFarlan Twin-Valve Six Roadster

The heart of the McFarlan Twin Valve Six is its massive engine with a 6-inch bore and a 4.5-inch stroke displacing 572 cubic inches - the largest displacement engine available in a production car for 1924. With four valves and three spark plugs per cylinder of its six cylinders, horsepower is rated at 120 bhp.

This rakish McFarlan roadster was initially purchased as a graduation gift for a daughter of the Goodrich tire family. In 1950, E.J. Leap of Hyndman, Pennsylvania, bought the car, and members of his family drove it on the 1951 Glidden Tour. Soon after, the car was partially disassembled and stored away for more than 50 years. Mark Smith purchased the car at auction, but it wasn't fully reassembled until passing into the hands of its current caretaker in 2017.
