I have an early 46 CJ2A with a supersonic engine in it. Does anyone know if this could have been the original Engine? I would think that there would be a ton of info out there. I am almost finished restoring a 56 MGA and there are times more detailed information on the web. Parts are cheeper too! Explain that!
War Jeeps are another matter. It covers most models but emphasizes the 3B. Go to the tech tips section and tell me you need more info. Or you can surf through the countless pages of photos and information. The 2A page is relatively new in comparison, is done strictly by volunteers and serves a very specific need for us with 2A's. Here's an example question so you know what I am talking about. What's up with the "kind of straight shifter" Vs. I know the later Jeeps were all straight but what's up with the early ones.
Belive it or not I was able to salvage all of the lights, switches, etc. Of course you know why the Brits. Lucas make their refrigerators. I can only guess that things went down hill after they built the MGA. New Posts. Members Profile. Post Reply. The kaiser supersonic is not original equipment in Willy's jeeps as Kaiser didn't buy Willys until either oror atleast right around there.
It is the same engine as the Jeeps, but not technically correct. Been down that road before! Thanks Madman, That's pretty much what I thought. It will be the page for your 2a as it develops. In the mean time there is alot of info and experiance on the G tech.
Ask about your details here and give it a chance we wait for a chalenge. Thanks guys. I will check out the pages that you both recommended.

Welcome to eWillys. I update this website nearly every day with jeep deals, jeep history, interesting reader projects, jeep related info, and more. These quick searches can help you find things on eBay. People list in the wrong categories all the time, so don't be surprised to see brochures in the parts area for example.
The links to posts below show jeeps grouped by models, condition, and other ways. Some of these jeeps are for sale and others have been sold. If you are unsure whether a vehicle is still for sale or not, email me at d [at] ewillys. There are plenty of interesting, unusual, historic and surprising stories related to Jeeps and their owners. In addition, some of these features have nothing to do with jeeps. This link will display all featured stories starting from the latest. Looking for parts and not sure where to go?
There are a variety of large and small new and used parts sellers both online and offline. Importantly, the allure of buying a project jeep can be romantic. The reality of restoring a jeep can be quite different, expensive and overwhelming without the right tools and resources. So, tread carefully when purchasing a "project".
If you have any concerns about buying a vintage jeep, or run across a scam, feel free to contact me for help, comments or concerns. Call Tom at for more info. Complete wire harness and dashboard for Willys Wagon or pick up truck.

I see no cracks or breaks in the castings. I separated the engine and gear box so they could be mounted on my engine stands.The parts book supplement indicates a "C" but none were produced to this authors knowledge. This engine was a clever rework of the old "Go Devil" Willys flathead 4 cylinder of the 's. Beginning engine number was 4P and continued consecutively, regardless of model year. It was also available in the early Larks that were converted fromas well as the and taxicabs.

The only response I have found was in answer to Joseph Dante who had a similar question regarding his CJ2A and about 40 messages about the difference between left and right hand threads NOW, can I possibly get some serious answers regarding the information I have to give the folks at the parts counters when I ask for a re-build kit for the beast???
Bernie Daily responded: If your engine is a flathead six with the distributor sticking right up through the head, it is the Continental 6, the L, same as the Kaiser. Walck's and Mendetz have all the parts you need. NAPA also has them, as well as most fork truck dealers. Prices are pretty much the same so support the hobby guys if you can. Rick LeBlanc responded: Testy, testy. You'll have to be patient with us as we're all here to learn as well.
Unbelievably, I have a '58 Chiltons manual. It appears you have a transplant form a Frazer car of Kaiser-Frazer as those engine serial numbers started in '50 at F-M "K" prefix for Kaiser, "F" for Fraser.
These numbers should have been located on a pad on the left front corner of engine block and on a plate on left side of the block. Kaiser engines didn't interchange from '51 to '54 so I believe these to be different then the ' Also, rebuild kit numbers are different between the Willys 6 and Kaiser-Frazer 6's.
I have an exploded pictorial of the engine assembly, I scan it and send it to you if you like. Wouldn't that look cool in your Wagon, eh? I would keep that engine you have if for nothing more then maintaining your Grandfather's legacy and with a little patience and research, you should be able to find the correct parts for it.
Jim Bartley? They sure sound similar. They have a NAPA parts list for some surprisingly cheap parts readily available for K-F-Willys cars if you know the right part number to ask for--after all, K-F-W bought a lot of parts from other suppliers rather than produce them themselves.
With some research, you might find that they fit the Jeeps too. Richard Grover wrote: I readily admit, I'm no master mechanic. I didn't take auto shop in high school, and while other guys were fixing up their 57 Chevy's, I was singing in the choir, taking advanced math, and in general being a nerd except lettering in track.
I assume many of you know more than I do about auto mechanics, and this is frequently borne out by responses to my posts and other notes. But I have lapped my valves with considerable benefit, so for those of you that are unfamiliar with the process, let me explain.
Anyone else with knowledge is welcome to jump in and correct me or fill in the thin places. My engine was running very rough. I had adjusted the intake valves about a year before, but didn't do the exhaust valves because I didn't dare pull the exhaust manifold on account of the badly rusted studs and nuts. Someone has since told me he adjusted his exhaust valves without pulling the manifold, but he admitted space was really tight. I removed the head from my F to find mildly burnt valves, with the exhaust being a little worse than the intakes, as I would have expected with my neglect of them.
If a valve doesn't seal tight, a small amount of hot combustion gases will escape. This high-pressure, hot gas erodes the surface of the valve and seat, leading to what is called burnt valves. Burnt valves don't seal tight, so the condition compounds itself. Looking at the beveled edge of the valves, I could see irregular dark blotches, not smooth shiny metal. With the valve springs removed, the valves are free to come out. It takes a valve spring compressor tool to relieve tension of the springs so you can remove the clips that hold the springs to the valves.It powered nearly all the Jeep vehicles built for the U.
Inthe Willys Quad was built to compete against the Bantam reconnaissance car for evaluation by the U.
The engine was developed by Willys' Chief Engineer, Delmar "Barney" Roosand was the most powerful of the three prototype vehicles evaluated by the U. Army for production. The engine displacement was It was an L-head design, with valves parallel to the cylinders.

To bring you light for your car. Wow, my last post had to go through a moderator. Unless someone swapped it, the '51 CJ-3 should have the L-head engine the flathead engine.
Kaiser and Willys were interchangeable back then, and a lot of one fit the other - with just minor differences in marking. While there may have been minor differences between Kaiser Supersonic and Willys Overland originally - at this late date they are the same. You probably have a garden variety L that someone swapped the head - or Willys borrowed parts from the other side of the house one week in Not at all unusual back then. I'm not sure on how much truth there was to it, but I read somewhere ewillys that the Kaiser Supersonic heads were thought of a performance enhancer.
The compression may be a bit higher, but I haven't noticed any difference in my 46 CJ2A. The Super sonic head was on there long before we bought it, but compared to other Willys L, they act about the same. My censored link mentioned an extra 5 hp and it was suggested it would have come from one of the Kaiser cars. AS you look through the really old stuff, Kaiser allegedly had different heads - like high altitude heads and such.
Supposedly, they were originally painted different colors - but the more suspicious of us believe that the biggest difference was the paint. I doubt that a different head would make that much difference.It was also used in the Willys and pickups, wagons, and sedan deliveries.
This engine was also built by Mitsubishi for their license-built Jeep, as well as other applications. The Hurricane was based on the earlier Go-Devil flathead engine. To get more power from the engine, the induction system was changed from the Go-Devil's side-valve configuration to an inlet-over-exhaust configuration, or "F-head".
This allowed the valves to be larger and the combustion chamber to be smaller, improving flow and increasing the compression ratio. The F was introduced in in the Jeep Truck. It was used in the Model Station Wagon. Its The compression ratio remained 7. It also had a slightly higher compression ratio of Later, after Ford acquired Willys-Overland do Brasil, they reverted the engine to its former head design with integral intake manifold, improved cooling between cylinders 5 and 6 and installed a side-mounted oil filter, instead of the front-mounted, hose connected arrangement used by Willys.
Mitsubishi built a version of the Hurricane from as the JH4 69 hpmostly for use in their license-built version of the Jeep. This was also turned into a 3. These diesel engines were used in the Jeep, but also in a number of light to medium-weight trucks and buses. From Wikipedia, the free encyclopedia. Willys Go-Devil Willys Lightning.
