The 1928 Cadillac received a new, larger V8 engine to replace the original one that dated back to 1915. This was a good year for the marque; production totaled 20,001 for the year. The Series 341 Cadillac rode on a 140-inch wheelbase, and the 341-cubic inch engine produced a top speed of 70 mph. The chassis had underslung rear springs, which allowed bodies to be lower than before. The 1928 model, which was the first Cadillac designed by Harley Earl, bore a distinct resemblance to the LaSalle introduced the prior year. No less than 42 standard body styles by Fisher or Fleetwood were listed in the catalog for 1928. This example is fitted with a custom Dual-Cowl Phaeton body by Fisher, and has been owned by Mr. Lewis for 15 years.
In 1928 Cadillac introduced a new V8 engine that was 341 cubic-inches and produced 90 horsepower. The vehicle in which is was installed was called the 341, or the Series 341 and 341B. Production of this engine, and this series, continued until 1929 when it was replaced by the 353. The Series 353 had a 353 cubic-inch engine which benefited from a 3.38 inch bore and 4.94 inch.
