1917 Cadillac 55 Club Roadster

Type 55 is similar to the 1916 Type 53 except:

Bodies

New crown fenders and elimination of molding on hood panels and around doors give smoother appearance overall.
Phaeton and Roadster have six degree slope to windshield.
Salon replaced by Phaeton with bench seat in front.
Club Roadster added.
Convertible Touring (a four door hardtop) manufactured by Cadillac and having a Vee windshield is introduced.
Coupe with cast Aluminum body is also manufactured by Cadillac.
Victoria is now five window with fixed top and removable pillars.
Berlin/Berline is now called Imperial (undoubtedly due to nasty connotation of “Berlin” at the time).
Landaulet body style added.
One listing of closed body styles by Fisher mentions “Touring Couplet,” with no description.
Previous round, plain door (rim) of headlights now embellished with stylized outline of shield and crown.

Chassis

Drive Line

Engine

Lighter pistons of “belted” design with large oil return holes in the piston walls.
Exhaust manifolds have shorter connector pipes.
Split, tapered collars used to retain valve spring feet.

Serial numbers were not used.
Engine numbers were stamped on the crankcase just back of the right hand bank of cylinders and on a plate on the dash.
Engine Numbers followed the pattern of two numbers, a letter, then a sequence number
The first two numbers represented the model (in this case ’55’)
The letter began with A and ended with S
The sequence number began with 1 and ended with 1000
- Thus 55-A-1 through 55-A-1000
- 55-B-1 through 55-B-1000
- 55-C-1 through 55-C-1000
- The sequence continued until 55-S-1 through 55-S-2
