Projects 52 MB with a Kaiser 161 engine need to decode

I am working on a friends 52 MB it has had an engine swap with a Kaiser engine cannot decode due to no available info I can find so far the block stamp code or serial # is 6P22416 the casting # is 649656-2 and I think the casting date code is 0 3 70 the head has 118 and 12 7 CWF

 

does anyone here speak English cars?

 

the 52-54 willys hurricane 6 codes I find (should be stamped on the front top of the block) start with things like 653-MA1

 

OK, I'm stupid, or without imagination. MB? Is that what I think it is?

 

Well that's an F head engine with the intake valves in the head and Exhaust valv

es in the block.
It looks like that is the Brazilian version of the engine with the dual single barrels Scroll down to F 161
https://en.wikipedia.org/wiki/Willys_Hurricane_engine It was known as a 2600.

Is the MB a W136?

 

If he would like to part with those carbs, I am looking for a pair

 

Pics of whole car would be nice and your location.

 

Some would say the car is O/T, looks like a hot rod to me. I love old Benzes, I had a W108 with the Bosch headlights when I lived in Venezuela, dual carbs and all. Wish I still had it, got stolen of course...

 

It's had an engine swap with an American designed engine even if the engine design is a bit off the wall. I'd say that makes it a hot rod.

Sounds like a normal hot rod building story from back when. I have this car with a cool body and a dead but expensive to repair engine and over here I have an engine that by the tape measure will fit in that space.

 

Well, first of all the car is an MG not an MB and the engine is definitely an F head and I know the early 161 Frazers were flat head Continentals and I'm somewhat sure the Nash engine in the Nash Healy was a pure overhead and I think the carbs were Carter YH's, so it may well be the Brazilian engine.

What are the carbs???

 

Ah so...now I have it. It's the F head engine and carbs? used in the Kaiser Darrin.

 

I also think this engine had an integral intake manifold like the Ford Falcon 6's and the head is modified to mount the dual carbs directly to the head. I'll look for the picture I have of a Kaiser Darrin engine close up to see if it's the same.

 

From what I just read about the Kaiser Darrin engines they were a little low on performance as used by Kaiser, after the brand folded some were re-fitted with multiple carburation .

 

Remember that MG was a 1250cc OHV engine or 75 cubic inches. Lots of V8-60's were transplanted, that's 135 inches but a flathead. I think that F head 6 with 161 inches is a neat transplant.

 

Ah...the plot thickens. Got to my photos of a Kaiser Darrin here in town that I took four years ago. I can't get them off my old computer without help, but, the Darrin did not have the dual side drafts. It had a single downdraft carburetor bolted to the top of the head.

So...has the pictured engine had the side of the head milled off, a plate made to cover the opening with two flanges to mount the still unknown carbs?

Original poster Ron...what are the carbs? Carters, but not YH's?

 

Oh! An MG! The puzzle is easier when you know what pieces you have.

 

If an MG with a Kaiser engine isnt a hot rod my whole notion about what a hot rod is just underwent a violent shock! That intake setup sure looks like a skilled machinists work ,not factory.Neat set up.

 

"No SBC???" LOL This worked-over F-head mill is as gr*** roots hot rod as it gets.
Bonus is that it's in a ROADSTER. (albeit one from the famous Morris Garages...)

 

OK, I cracked the code.

Here are the photos of the Willys 161 6cyl F head in a Kaiser Darrin in a friends local car collection. Note how the stock carburetor mounts directly to the head and the nice 6 port exhaust is coming out of the block not the head.

 

ok... I know this is an old post, but ... As many have commented, the motor is a Willys F-head.. BUT!! the intake side of the head has been modified (no, it is not the Brazilian dual carb head). Years ago I came across an article in Speed Mechanics magazine (Feb 1956 issue) named "souping the Willys". This was not the same engine (based on some photos of intake mods) that you have in the MG.. I did also come across a small insert in the October 1952 issue of Speed Age magazine (Willys powered MG was insert headline). This insert looks to be THE car and motor you have. I could be wrong, as there might have been more then one modified this way? The MG was owned (stated) by Mrs. Marvin Lowe from Santa Cruz, CA. Car was run at Golden Gate Road Race driven by Bill Stroppe (owner of the shop Automotive Research of Long Beach, CA that modified motor and did install) - and took 2nd place to Phil Hill's Ferrari. The insert in Speed Age was on page 70. Hope this helps!
