This Model T Speedster was developed for racing in the United Kingdom using high performance parts, including the famous Frontenac cylinder head invented by the Chevrolet Brothers. It made four-cylinder engines competitive in racing. Builders of Ford-based race cars found it perfect for the Model T power plant.
There is a story, not fully authenticated, that a Frontenac Model T race car was built by Alfred Moss, the father of British racing driver Stirling Moss, to campaign in the United Kingdom. The story says it was raced on both sand and board tracks. The power plant is an inline, 4-cylinder, 122 cubic-inch engine with 2-valves per cylinder, developing 80 horsepower at 4000 rpm, compared to the standard Model T engine producing only 20 horsepower.
