1934 Cadillac Model 355

The1934 Cadillacs were completely restyled and mounted on an entirely new chassis, but used the same basic engines as in 1933.


  • Bodies on the Series 10 and 20 cars were built by Fisher.
  • Bodies on the V-8 Fleetwood Series were shared with the twelves and sixteens.
  • Styling emphasized streamlining including concealment of all chassis features except the wheels
  • Body construction was improved for better insulation against engine heat and reduction of engine, road, and wind noise.
  • Bumpers were a stylish but ineffective biplane design, mounted against telescoping springs.
  • The grill was Vee shaped and sloping, set into a painted shell.
  • Although restricted use of chrome was a feature of the overall ornamentation, a chrome plated radiator shell was available as an option.
  • Horns and radiator filler cap were concealed under the hood.
  • Teardrop Guide Multibeam headlights were mounted on streamlined supports attached to the fenders.
  • Parking lamps were mounted in the headlight supports.
  • Airfoil shaped front fenders were brought low over the chassis.
  • The hood sills were high, with the entire fender shape molded into the radiator shell.
  • A curious horizontal crease broke the nose contour of the fenders.
  • Hoods extending nearly to the windshield carried shutter type louvers in the side panel.
  • Windshields were fixed and steeply sloping; 18 degrees flat on Fisher bodies, 25 degrees flat or 29-1/2 degrees Vee on Fleetwood bodies.
  • Cowl vents opened toward the windshield; one vent on flat windshield bodies, two vents projecting through openings in the hood on Vee windshield bodies.
  • Bodies were two inches lower than on previous models.
  • Added passenger space in the front compartment was achieved by moving the hand brake lever to the left of the driver, under the instrument panel.
  • On twelves and sixteens, the gearshift lever was moved forward to the clutch housing.
  • Rear fenders were airfoil shaped and carried rear lights which matched the headlights.
  • The gas tank filler on Fisher bodies was on the left side at the rear of the body; on Fleetwood bodies in the left rear fender.
  • All bodies featured a beaver tail rear deck which completely covered the chassis.
  • On Fleetwood bodies, the spare was concealed inside the rear deck, unless optional fender mounts were specified.


  • Significant changes in chassis design resulted in improved riding and handling plus decreased driver fatigue.
  • The new independent “knee action” front suspension with coil springs and center point steering resulted in greatly reduced unsprung weight.
  • Front shocks were now an integral part of the suspension; the shock arm being the upper suspension arm.
  • An inverted steering box, mounted on the outside of the frame, was used on Fleetwood bodied cars.
  • Hotchkiss drive replaced the torque tube drive.
  • Rear brakes were operated by pull rods and cables.
  • A new frame of X design added to chassis strength and allowed for the reduction in overall vehicle height.
  • A stabilizer bar to control body roll in turns was added at the rear of the chassis.
  • The brake and clutch pedal assembly was relocated from transmission to frame.
  • Mufflers on Fleetwood bodied cars were relocated to the outside of the frame.
  • In Fisher bodies, the battery was under the front seat, on the right side.
  • In the Fleetwood bodies, the battery was under the right front fender and was removed from underneath.


  • Engine changes were few, but horsepower was increased.
  • All engines used Lynite Aluminum pistons.
  • Compression ratios were increased.
  • Intake ducting to the carburetor air cleaner was extended to the radiator casing, providing cold, dense air rather than the hot air in the engine compartment.
  • The combination of Aluminum pistons, cold intake air, and higher compression with improved fuels resulted in increased horsepower and engine speeds.
  • Detail changes in the V-8 engine included a change to the Detroit Lubricator Carburetor, use of dual valve springs, discontinuation of the oil filter, and solenoid starter control with starter button on instrument panel.
  • One V-8 engine change to be appreciated by anyone removing a cylinder head was the change from head studs to cap screws.
  • The change was actually made so that the heads could be turned before lifting, so as to clear the hood shelf.
  • Another change, not necessarily appreciated was the elimination of provision for hand cranking.


  • Serial numbers were on top surface of frame side bar, right side, of dash.
  • Same as engine number.
  • Starting no.: 3100001.
  • Ending: 3108318 (with 1935).
  • Engine numbers were stamped on crankcase near the water inlet on the side.
  • Starting engine no.: 3100001.
  • Ending: 3108318 (with 1935).

  • Some confusion exists regarding style numbers on 1934-35 Fleetwood bodies.
  • Following the previous Fleetwood system, V-8’s would be 56- or 60- styles, V-12’s would be 57- or 61- styles, and V-16’s would be 58- or 60- styles.
  • This system was followed in promotional literature, in the 1934 Master Parts List, and in early factory records.
  • However, since the bodies were identical for all these series, Fleetwood stamped all body plates 57- or 60-.
  • Master Parts Lists after 1934 used only 57- and 60- style numbers for 1934-35 Fleetwood bodies.
  • Starting in 1936, V-8 and V-12 style numbers reflected the new 1936 series designations, but V-16’s retained the 57- system. However, 60- styles were no longer offered.
