1931 Cadillac Series 370-A Twelve

Cadillac 1931 Cadillac Series 370-A Twelve History Specifications
Share On

In 1930 Cadillac started a 'Cylinder Race' by introducing an overhead valve, 452 cubic-inch V-16 engine. Marmon followed suit with a V-16. In 1931 Cadillac introduced a V-12 resulting in its having a V-8, a V-12, and a V-16 engine. By 1932 several other luxury brands, such as Lincoln, Pierce Arrow, Packard, and Auburn, joined the race with V-12 engines. By 1931 Cadillac offered more models and body styles than any other make with 3 wheelbase lengths, 3 engines, and over 60 body styles both production and custom.

The 1931 V-12 Model 370 has a 140-inch wheelbase chassis with a 368 cubic-inch, 135-horsepower, overhead valve engine. It incorporates unique hydraulic valve lash adjusters, among the first engines with this feature. A Cadillac V-12 roadster was the Pace Car for the 1931 Indianapolis 500. Most enthusiasts who have driven good examples of the V-16 and V-12 feel that the V-12 is a better driving car, partly as a result of the much lower weight on the front end, with almost as much acceleration and speed as the V-16.

This Convertible Coupe was purchased by the present owner in June 2012. After driving it about 20 times for evaluation a complete restoration was started. It is a correct authentic restoration with matching engine, transmission, and body numbers.
