1948→1958 Stanguellini 750 Sport Internazionale
Built alongside the larger and faster 1100, the 750 was Stanguellini’s smallest sports racecar. It used a highly advanced twin-cam engine which produced over 100 bhp per liter. Because of this, the 750’s engine was used in numerous other cars and became Stanguellini’s most revered design.
The absolute highlight of the 750 was it’s engine designed by Oberdan Golfieri. It was a highly tuned inline-four that used semi-domed pistons and twin overhead cams for optimum combustion shape. Later versions were built out of aluminum, with cooling fins on the oil pan and filter. By 1955 a short-stroke unit was fitted in the the Sport Internazionale.
At first the Stanguellini was fitted with Spider Corsa bodywork similar to the Ferrari with detachable fenders. In 1953, the Italian regulations outlawed cycle wings, so all enveloping fenders were fitted with large fasteners for quick removal. Ocassionally the lights was fitted inside the small front grill.
