1929 Cadillac V-8 Seven-Passenger Imperial Sedan
Cadillac introduced synchromesh gearing for 1929, eliminating the need for double-clutching when shifting between second and third gears. This “Silent Synchro-Mesh” transmission represented a significant advance in drivability, allowing chauffeurs to operate the heavy formal sedans with considerably less effort.
The Seven-Passenger Imperial Sedan (Fisher body style 8630) featured a glass division window separating the driver’s compartment from the rear passenger area, along with two folding jump seats for staff or additional passengers. Pricing started at $3,895, positioning it as the most expensive Fisher-bodied configuration.
Built on a 140-inch wheelbase, the Series 341-B received subtle styling revisions including parking lamps relocated from the cowl to the fender tops. New Duplex mechanical four-wheel brakes with internal expanding shoes required less pedal pressure than previous designs.
The 341-cubic-inch L-head V8 produced 90 horsepower and used a cast-iron block and crankcase with aluminum pistons. Security-Plate safety glass became standard across all windows, while double-acting Delco shock absorbers and fully adjustable front seats improved comfort.
Combined production of the 341-A and 341-B totaled 18,004 units before the Series 353 replaced them for 1930.
