By the early 1920s, the Cadillac V8 engine was a tried-and-true piece of machinery. Over 160,000 examples had been produced by the close of 1923 which included around 2,000 staff cars used during the First World War. Under the direction of the newly appointed chief engineer, Ernest Seaholm, the V8 engine was redesigned. Up to this point in history, the V8 was assembled as two four-cylinder engines on a common 'flat' crankshaft. It worked, but suffered from imbalance.
Cadillac introduced their newly re-designed V8 engine for 1924. It was balanced, had two-plane crankshaft, counterweighed with rod journals at 90-degrees t one another. This is the same way V8 engines are made today. The result was a very smooth engine that produced more power - thanks, in part, to a lighter flywheel.
Cadillac introduced four-wheel braking to their new V-63 model. It was mechanical while other marques, such as Duesenberg and Chrysler, used hydraulic braking.
This 1924 Cadillac Opera Coupe is powered by a 314.5 cubic-inch L-head V8 engine that is capable of producing 83 horsepower. There is a three-speed manual gearbox and four-wheel mechanical brakes. It has been treated to a high-quality restoration in the late 1970s and has been carefully maintained since that time. It is painted in tan with black fenders. The interior is brown mohair. It has the standard equipment Kellogg tire pump on the transmission, and an extendable trouble light. The rear of the car features a small luggage compartment, accessed from above the aft-mounted spare tire.
