Built for Gulf Oil to race at Indy in 1938 Miller's design was four cylinders and four wheel drive. The FWD made the cars look high and ungainly. The tubing on the top half served as the radiator with the bottom an oil cooler. The first time out the car overheated and Miller went to two ugly, externally side mounted radiator cores. Harry's brakes operated like a clutch disc and a pressure plate, a concept eventually used by Joe Milan on what became the Kinmont disc brake and Chrysler tried a similar brake on the 1950 Imperial.
