Website Feedback / Re: Post Count Not Working

tow hook,
Did you try the same test above?  Pascal noted his count, then posted to see the increase.  Perhaps your total is low based on the glitch that was reported by Stingray 2 yrs ago.  Pascal must've made an adjustment back in June.  I'm posting to check my own to see if they increased.

Mine did not.  Stuck at 339.

EVERYTHING ELSE, General tips / Re: engine swap to a kasier flat head

« Last post by Mark W. on September 11, 2026, 12:03:43 PM »

A Kaiser Super sonic is a Willys 134L with a high compression head and a larger carburetor. The only physical difference is in the combustion chambers. Oh and it would have come with a Vacuum Advance distributor which if the vacuum can is working is a nice upgrade. If the Vacuum can is shot then its costly to replace one. As to bolting right in as long as the Front engine plate is from a CJ either 2A or if your jeep is a 3A then a 3A plate it will fit.

EVERYTHING ELSE, General tips / engine swap to a kasier flat head

« Last post by tow hook on September 11, 2026, 11:40:22 AM »

So when i got my 2a i knew it had a ruff life.  every drive train component that i ve worked on has been over hauled so far. It's all been not just a fast rebuild either. it's needed the whole parts book.  The engine is no different. multiple types of valves are in the head, no compression, worn out etc. the owner of the jeep 2 owners ago sent me a message to buy a flat head in the back corner of the garage he had. ( the engine came with the jeep ) So i did, it's freed up. as i get time i'll pull the oil pan and go threw it. i hope it's a runner. or at the very least cost less the finish then the go devil that's in the 2a now. thoughts on how easy this is to swap ? should just bolt in ?

EVERYTHING ELSE, General tips / Re: Speedo reads at 1/2 speed

« Last post by tow hook on September 11, 2026, 11:16:14 AM »

Any feed back on this speedo on a CJ3a.    Purchased with a complete gage set but reads at 1/2 speed against my GPS.  0-60 with MS 39021-2 label.   Am running 16" NDT's    Not sure if the Dana 44 is a 4.27 or 5.38 but still would not make that big a difference.   Any ideas would be appreciated

 i had the same issue.... i found that my cable was to long and bound up,, the needle would hand up and stick. the took off a 1/8" at a time ( down at the t case ) till it was right. and checked it with gps as well

I see this is your first post!  Welcome!

Currently, does your CJ-3A have an engine?  It almost sounds like you may not. What about the rest of the drivetrain?

If the company you're corresponding with is state-side, they should absolutely have documentation on the L-head - and its multiple applications.  If they are overseas, I'm just going to say, "Buyer Beware."  With overseas, you could finally get the engine but may still end up with a pricey boat anchor or still have to spend extra to get it to fit and work.

But to answer,

Pictures are great.  The phrase, "A pictures speaks a thousand words," comes to mind.

The Service Manual is great for understanding/repairing but most of the images within are exploded or cutaway.  It may be that you'll need some data on the engine from the "Specifications" section, Section D.  Have you scoured the 3A page, the 3A info page?  You may find some engine images embedded within.  Also, there are some images on the CJ2A Forum since they also use the flat-head engine.

An alternative...

It sounds like you don't want to, or can't, do any engine refurbishing.  You can get a used engine that may just drop in and run.  Or you may find one that is in desperate need of rebuilding. 
Having a known CJ3A/CJ2A engine with all the attachments needed to function in your jeep may be worth the trouble - even if it needs rebuilding. 

Your post didn't give any insight as to where you intend to go with your project.  Some want a 12V conversion with an alternator.  Some have even stuffed a 134 F-head under the hood, both with and without cutting the hood.

Share more information including where you're thinking about getting this engine from as well as your general location.  Others here may be able to provide you with better intel on where you are and where you want to be, or there may be a nearby neighbor who has a spare engine in the barn. 

I mention this as there is a Fall Reunion approaching fast and there was a member on the 2A forum who stated he had 2 spare engines.

Can you post an image of your jeep?

I have been looking for an Engine for my CJ-3a 1951 Willys Jeep. I contacted a company, told them the year and model of my jeep so they sent me pics of engines (rebuilt) but they don't look like my engine. How do I give them correct information to get the correct engine? Is there something I am missing?

The hood has been a project. The center seam had rust pushing it apart, so drilled out the welds and clean all of that out. Then the metal was so thin the center had very little support and needed some reinforcement, so I made some angles to weld in. Lots of grinding, working the small dents and some primer, I think the metal work is pretty much finished.
