Carroll Shelby drove one of the Scarab sports cars to victory at Continental Divide Raceways in Castle Rock, Colorado, setting a new course record.
[2] They featured desmodromic valve gear similar in design to that found on the Mercedes F1 engine of the 1950s and were built and maintained by Travers and Coon.
Both Scarabs were entered in the Grands Prix of Monaco (where they suffered hydraulic brake fluid aeration problems and did not qualify for the race), Holland, Belgium, and France (where both Daigh and Ginther experienced oil starvation issues resulting in burnt bearings), while only Daigh's car was entered in the final race of the 1960 F1 season, the American Grand Prix at Riverside, California (the Scarabs' home track).
Scarab built one rear engine car for the 1962 season, powered by a Buick aluminum V-8 with Phil Remington fabricated intake and exhaust manifolds.
So, he went to the California Department of Motor Vehicles and (after installing a muffler) managed to get license plates for this all-out racing car.
[1] Reventlow was planning on closing down the Scarab operation so he sold this little sports racing car to John Mecom Jr. of Houston, Texas.
