To turn the 1953 Corvette into a high-performance sports car, McCulloch Motors created an experimental supercharged model. Two such cars were developed as a possible solution to raise the specific output of original ‘blue flame’ inline-6 that produced less horsepower than the competing Ford Thunderbird. While the design was somewhat clumsy, power increased 35% from 87 to 117 bhp. At the time, McCulloch & GM listed the power output of 150 bhp. The performance increase meant that 0-60 times was reduced from 12 to 9 seconds. Proposed to GM as a possible factory option, the supercharger was never put into production.
