Posting today is two photos of the Spalding bros Av8. The unusual V8 is a 1930s Riley SOHC V8 which used stock '34 ford V8 crank, rods, pistons. The SOHC engine in these photos was owned by Eugene Von Arx, who also owned a Riley OHV V8 which was run in his Frank Kurtis built custom. After Tom & Bill sold their AV8 they built their famous #43 track roadster. The A roadster is apparently the survivor roadster of Tom Morris, Tom apparently purchased the car from the Spaldings.
