This 1977 Porsche 911 Carrera 3.0 was a European-market example that was backdated to look like a 1973 Carrera RS. Although its original pale yellow finished was changed to Signal Yellow as part of the process, the car still retains the factory steel Carrera 3.0 flares. The front fenders have been modified to resemble a long-hood car and a factory steel long hood and early-style turn signals and horn grilles were also installed.
The original 3.0-liter CIS engine was replaced by a carbureted big-port 930/10 flat-six which can put out 221 horsepower and 199 lb-ft of torque on a dyno run.
