31 Coupe


1931 Sport Coupe

The ’31 Chevy is an AE Independence Sport Coupe.  The Sport Coupe model was different than the standard five window coupe in that it had a rumble seat, cowl lights and pin striping.

I purchased this Chevy in 2009 from a fellow in Michigan who was liquidating his collection of cars.  The paint and interior of the car are in excellent restored condition.  It is equipped with the original 194 cubic inch in-line six cylinder engine and three speed non syncromesh transmission.  The car was built in Janesville, WI in June of 1931.  The color scheme (Harvard Crimson and Black) is as the car came from the factory even though it has been repainted.

The car ran relatively well when it was delivered but had a bad tendency to overheat after seven or eight miles and the transmission clashed badly when shifting into first gear.  Also, the car had a tendency to bog down at certain points during acceleration.  Unfortunately the test drive before purchase was insufficient to discover the problems early on.

The acceleration problem was fairly easily solved by having the updraft carburetor rebuilt.

The overheating problem was especially problematic as it limited enjoyment of the car and caused worry over potential damage to the engine.  I first tried the usual route by having the radiator removed, tested and a small leak repaired.  I had the water pump rebuilt and the cooling system flushed.  Although there was some improvement, the car still overheated.  I resigned myself to having the engine removed and torn apart to solve the problem.

After bemoaning the fact one evening with a good friend, Rick, who was a fellow member of our local Corvette club, I got a call from him a few days later.  He said, “why don’t we check the timing before going through the expense of the engine work.”  It was a pleasant summer day, we were both free, so, even though I felt it was a waste of time, I told him to come on over.

Rick had researched the correct timing on a website called http://www.1931Chevrolet.com.  The web site is a wonderful source of information on 1931 Chevys.  When we checked the initial timing we found it was far off the recommended 18 degree advance.  After adjusting the distributor we were able to get the timing close to the recommendation.  We also gapped the spark plugs to the recommended 0.040 inches.

When we fired up the engine it sounded better to the ear, but the true test remained a long drive on a hot day.  An initial trial showed that after twelve miles the temperature gage stayed well within the normal range.  A next day 45 mile trip on a very warm day resulted in the same normal water temperature.  It appeared that the problem had been solved.  Subsequent driving to shows, for pleasure and even in parades has proven that the car is now reliable under all conditions.

It’s all in the timing.

The shifting problem was diagnosed with Rick’s help as a worn throw out bearing.  A call to The Filling Station produced a NOS (believe it or not) throw out bearing. Installation of the new bearing resulted in smooth reliable shifting.  The car was now a true pleasure to drive.

On the cosmetic side, I restored the engine compartment and added the correct pin striping.  The engine compartment was relatively clean but needed repainting. Again, with the help of The Filling Station, I was able to get the correct blue-gray engine paint and a copy of the original factory drawing that showed the correct application of pin striping for a sport coupe.  Both jobs were a lot of fun and I can modestly say turned out quite well.

There are two reasons why a car of this era was purchased in the first place.  Early in the spring of 2008 while attending a car show in Hilton Head Island, SC with my wife and her friend, the ladies remarked how “cute” a couple of cars looked with rumble seats.  That comment opened the door, and any red blooded car guy who doesn’t take advantage of even a small opening is missing a great chance to add another vehicle to the collection.

The second reason I decided to buy the car is my father-in-law.  John is a great guy who was born in Finland and drove a similar vintage Chevy there before immigrating to the United States in the ’50s.  The car would be a source of enjoyment and recollection of memories for him.  My mother-in-law also has a kinship to the car since she was born a month after the Chevy was built.  John has driven the car to numerous shows and almost always comes home with a trophy. Listening to him answer questions about the car and watching him proudly walk up to pick up his award always brings a smile to my face.  His enjoyment of the car is a special treat.

John and the ’31


  1. Phil, it’s fun to read the stories on each of the cars. Good job taking advantage of the “rumble seat” opening to leverage the ’31! Switching topics, I’m interested to hear more about the timing problem. Have to talk to you and Rick about the details sometime. I assume it was advanced too far previously, causing the overheating.

    • Ken, I don’t recall whether the timing was advanced too far originally. I am trying to see if Rick remembers. The timing was manually adjustable by pulling a knob on the dash to retard the spark during starting. Our 18 degree advance is set with the knob pushed all the way in. The car starts fine without any other adjustment of the knob. Part of the timing adjustment was an additional recommendation to regap the plugs to 0.040 inches. That was done after the timing was adjusted. Hope this helps. Phil

  2. looking to convert my 1931 chevy 5 window business coupe with trunk, to a rumble seat. Need all components and hardware. any info on were to locate, or if you have any material.

    • Todd, My ’31 came with the rumble seat as part of the sport coupe package, but as I look at it, conversion of a trunk to a rumble seat looks doable. I would give the guys at The Filling Station a call. They are very knowledgeable about Chevys of this vintage and I have found them to be friendly and helpful as I ask a lot of dumb questions. A little more problematic may be the crank operated rear window on the sport coupe. I was told that the window facilitated conversation between front seat occupants and those in the rumble seat. There is also a pull down blind on the window that I suppose let’s you really tune out the rumbles seaters. If your five seater already has the crank operated window, you’re part way there. Maybe the window was for a primitive form of Astro Ventillation and had nothing to do with rumble seat occupants. Let me know how you do.

  3. Hey Phil Car looks great with the rest of the line up does your wife no.p.s I do know who the mechanic is in the picture. Larry

  4. Can you tell me where the VIN# is located on the body?
    Thank you,

    • Steve, The vin tag is located on the floor of the passenger side of the vehicle. If you pull up the floor mat under the passenger’s side you will find it.

  5. Phil it was just great meeting and talking with you at the Middlefield car show. Congratulations on your win there. I appreciated all that you said about my 1931 Chevy Cabriolet and look forward to learning more about it. It looks as if I will be spending much more time with my car due to your encouraging words. I will have my boys put pictures on my web site in the upcoming weeks.

    • Ken,
      Thanks for the good words. You’ve got a beautiful 31 Chevy. I’m glad you also won an award. You deserved it. Now, get cracking on that engine compartment!
      If I can help let me know. Make sure to let me know when you’re in the area so we can arrange a garage tour. Keep in touch. Phil

  6. Dear Phil. This is one of the most beautiful Chevrolet 1931 you can find picture of on the internet. First picture is gorgeous. What a great looking car. I own a 1931 coupe in Reykjavik, Iceland and would like to paint it red. Is it possible that you could have some paint number or any informations to work on to find that color you have on your car and have it mixed by some paint dealer.? I have been trying to look at color chips now for to many days and that is blowing my mind. I only see ugly colors by doing that. HEHE

    • Runar, Thank you for your nice comments. It’s great to hear from someone in Iceland! My wife is from Finland-sort of in your neighborhood.
      The body color is the original (but repainted) Harvard Crimson. The wheels are Cream Medium and the engine is the correct blue/gray. A lot of guys incorrectly paint the engine in Chevy blue. That’s too much blue.
      A great on line source that I have used many times is http://www.1931chevrolet.com. There is loads of information on that site about 1931 Chevys. There’s a link to it on my web site. According to them, an excellent match for Harvard Crimson is a 1968 Fiat color #189 or DuPont 8284L,99573. The medium cream color match is PPG C6004K. At first it looks a little yellow, but when you put the wheels back on the car they look super. The correct engine paint came from The Filling Station in Oregon. Those guys have a web site and print catalog you can order. It’s full of parts for Chevys of the 30s. I have also called them on several occasions for advice.
      I always enjoy hearing from fellow Chevy collectors. Having one from Iceland contact me is a special treat. Good luck on your restoration. If you need any other help, don’t hesitate to contact me. Send me photos of your project, and I’ll post them on the web site.
