1966 Shelby Mustang GT350 Coupe

  • Chassis Number: SFM6S342
The Shelby Mustang was a streetable half-step towards the car he really wanted to race - the GT350R, with the 'R' signifying its racing specification. The production GT350 had the suspension, steering, and brakes necessary to make it suitable for SCCA competition. The R-model engines were built to order. They had heads ported and polished by Valley Head Service, Tri-Y headers by Cyclone, a center-pivot-float Holley 715 CFM carburetor on a Cobra intake and flow-through side-exit exhaust. The power produced by the engine ranged from 325 to 360 BHP on the Shelby dynamometer. Differential and engine oil coolers were added, the latter necessitating the distinctive fiberglass front valence that distinguished the R-model. The side and rear windows were made of Plexiglas and the fenders were flared to accommodate wider Goodyear racing tires. Inside was a four-point rollbar welded for safety. They had a quick-fill 37-gallon fuel taken fitted in the trunk. When it entered the SCCA B-Production competition, it quickly became the car to beat. In total, Shelby produced just 34 examples of the GT350R.

Several production GT350 models were converted in a similar fashion to Shelby's winning GT350R formula. A few even sprung up across the ocean in Britain and Europe. One of those was this 1966 GT350 which was owned and raced by Swiss driver Herbert Muller from 1966 through the early 1970s. It is a European export model shipped to Ford Advanced Vehicles in Slough, England. It was modified with R-Model type racing equipment including a roll bar, oil cooler, 37-gallon fuel tank, fiberglass front valence, American Racing Torque Thrust 'D' alloy wheels, and a Weber-inducted GT40 engine built by Holman-Moody.

Mr. Muller began his racing career in 1959 racing motorcycles. He later competed in European hillclimb events. Driving a series of Porsche GT racers, he became especially successful in the FIA European Hillclimb Championship, winning the GT Championship in 1963. He would become an experienced and accomplished driver in the world of sports and prototype racing until his death at the Nurburgring in 1981.

After his passing, Müller's personal car collection sat dormant until 1985, when Ron Randolph, a civil engineer with the Army Corps of Engineers in Frankfurt and an accomplished restorer of vintage sports cars, learned of the Müller GT350 through exotic car dealer Auto Exclusiv of Zurich, Switzerland, whom Müller's son had asked to broker its sale. After purchasing the car, Randolph and his friend Rich Bard worked over 600 hours to complete a restoration on the car. It was stripped down to bare metal, and repainted in the original Wimbledon White with Guards Blue stripes. Many mechanical components were reworked or rebuilt including the engine, suspension, and brakes.

The restoration was completed in time for the August 1986 Nurburgring Historic race. The car was subsequently raced regularly by Randolph before being put on display at the Nurburgring Race Car Museum. It later was put on display in Peter Kaus' Rosso Bianco Collection in Aschaffenburg, Germany in 1988. It remained there for 18 years before Randolph once again assumed its care and maintenance.

The car currently retains its Holman-Moody-built GT40 engine and is configured as it was when delivered by Ford Advanced Vehicles. It is officially listed as an Independent GT350 Racer in the Shelby Registry.
