Abarth’s successful small bore race cars dominated racing in the late 1950s and into the 1960s with over 700 wins worldwide. The Record Monza was one of the most successful versions, including in the US at events like the 12 hours of Sebring. Based on a design by Zagato, they featured very light weight tube frames grafted onto the floorpan of a Fiat 600, then covered with a sleek, aerodynamic aluminum body. The Bialbero engine was introduced first in the Record Monza as a 750cc powerplant. Though later bored out to 850cc and 1 liter variants. Based on the Fiat 600 block, it features an Abarth-specific twin overhead cam head with hemispherical combustion chambers, designed with input from Gioacchino Colombo, who also designed Ferrari’s V12 engine in the 1950s.
This car is a project car in line for a future restoration that will be beginning shortly. As was the case with just about every Bialbero engined Abarth, this car has been a race car for its entire life and at one point had poorly executed flared fenders fitted to allow for very wide tires. In the restoration, our goal is to reverse that process and return the car to its original shape as much as possible. In addition, with an aluminum body on a steel frame, these cars often suffer from electrolytic corrosion, requiring extensive work to properly repair and prevent the corrosion’s return. Although I own an early single cam 750 Record Monza as well, the Bialbero engined models were the peak of the development of the design. As the restoration progresses I hope to continue to share photos and details here.
