With financial backing from the Stutz Motor Company, engineer and racing driver Frank Lockhart built a streamliner called the "Stutz Black Hawk Special" to challenge the Land speed record. The engine for the car was built by Riley Brett. The powerplant consisted of two Miller 91 top ends mounted to a common crankcase at a 35° degree angle. The cylinder banks retained their individual crankshafts, which were geared together in the crankcase, with power leaving via an output gear mounted low in the case. The combined engines were supercharged, and Lockhart added two intercoolers. On April 25, 1928 the car went out of control during the return run of a record attempt at Daytona Beach, throwing Lockhart out to his death. The engine was salvaged, and later became the basis upon which the Sampson IC-30 Indy car of 1930 was built. Goossen became involved in the project at this time, working with Brett to design a new underslung chassis of box-section aluminum for the car. The front suspension used parallel quarter-elliptic leaf springs, while at the rear a De Dion tube was suspended on parallel torsion bars. The car appeared at the 1930 Indianapolis 500 for the first running of the so-called "Junk Formula". Driven by Louis Meyer, it took an early lead but had to pit for repairs. The car finished fourth.
