Spotted - 1929 Royce-Hispano H3 Aero-engined Special

A massive 18.5 liter H3 V8 with 360bhp and just under 1000lb/ft of torque is the calling card of this unique automobile. A power plant derived from Hispano-Suiza's H3 line of aircraft engines built under license by Wright Aeronautical Corporation in 1922. The chassis? A Rolls Royce 20/25 (source). This car is one of the most unique "classics" to roll in front of my lens this year. I read it took 10 years to make this project come together. It can only be rivaled by the other "special" that we saw that day. That one however is another story...
