Description for Cadillac 341 B 1929

1929 Cadillac 341B Boattail Roadster

You're looking at a custom-bodied 1929 Cadillac 341B Roadster. It’s unclear when the boat tail modifications were done to this car, but the work is quite old (extensive lead work on the top of the doors, trunk and door latches were granted patent 1,771,737 on July 29, 1930, and the custom interior has already been redone at least once). I've done my best to represent the car below, but feel free to call or text if you want additional info or pictures: 512.653.0773

This car is a reliable daily driver for those insane enough to drive a 91 year-old car that doesn’t have side windows on a daily basis; I am that insane (my other car is a 1930 Model A Ford hotrod). That said, you’re not going to be getting out on the highway (it has a rear gear ratio of 5.08:1 — comfortably cruises at 40 mph). It's far from perfect, but damn it's FUN.


The history I have goes back to when it was sold for $28k at the Kruse Auburn Auction on Saturday September 2nd, 1989 (lot #646). The owner prior to that auction lived in Grand Rapids, Michigan with the last name of Tudder.

The car sat in a warehouse from ~2007 until late 2019 when I acquired the car; it was parked due to the deterioration of the wiring harness and two of the wooden wheels becoming wobbly. I do not know when the restored 20” Houk Wire Wheels (later, American Wire Wheel Company) and hubs were purchased, but they were with the car when I bought it (not mounted).


Extensive effort went to reviving the car and are as follows:

  • New wiring harness throughout — all original metal conduit used for the new wire with the exception of the tail light and fuel sending harness (old conduit was left in place, but new plastic conduit was run along side it).
  • Rebuilt Carter BB-1 updraft carburetor;
  • Valve lash adjustment;
  • NOS points (dual), new cap, rotor, coil, and condenser;
  • New tires (Lester), tubes, and flaps;
  • Steel brake drums were turned;
  • Brake shoes relined with correct woven material (Austin Brake Clutch and Supply);
  • Mechanical brake mechanisms were inspected and operate as they should;
  • New exhaust system from the manifold back (Muffin Muffler);
  • Radiator was gone through and leak checked by a shop (City Radiator Service);
  • New Carter 6V vane rotary fuel pump with Holley fuel pressure regulator (set to 2psi) that runs off an engine oil pressure switch (set to 4 psi);
  • 6V redtop optima battery;
  • Rebuilt generator;
  • New fuel tank sender and rebuilt fuel gauge;
  • Rebuilt amp gauge.

The exterior looks good from 10 feet and is far from perfect -- scratches, checks, chipped paint, a few bubble here and there. The boat tail section is all metal laid over wood (just like the original sections of the car). Original primary color was a dark green. The car comes with the factory wire wheel carrier for the rear, but it is not currently installed (pictured on the car in the last few images below).


The interior features two bucket seats that lean forward to reveal a very small storage space. The door panels and seats are in decent shape -- couple small cracks in the material in some places, but no rips or tears. All gauges work as they should, all switches work (lighting, etc.), and at some point in history someone removed the clock (which is included) and put a motometer vacuum gauge in its place. The convertible top works as it should and has no holes in it.
