230 flat 6 headgasket fitting issue
-
So I finally got it into the garage and tore into the head gasket on my 1950 dodge meadowbrook with a 230 l-head straight 6. Getting it apart was easy as pie, and everything tested a-o.k. and looked clean as a whistle. New gaskets showed up from fel-pro and DAMMIT!!! They are fel-pros set for the 1950 meadowbrook but they really don't even come close to fitting. I have alot of paperwork for this car and I show no mention of it being a canadian or of ever having an engine swap. So... Anybody wanna take a crack at what is going on. This felpro gasket, in addition to being too small has a little nub at the back that is all wrong for my engine here is a picture...
I would send a picture of my old one but now I can't find it. Same as above but longer and no nub.
Somebody HELP!!!!

Jack;
First off there are two different gaskets available for the flat 6. The one you have pictured is for an internal by-pass water pump. There is a gasket without the extra hole on the front for an external by pass water pump. The nub does install towards the front of the engine for the internal by-pass configuration.
Now for the bigger question. It is unclear from your posting what engine you have. First thing to do is measure your head from front to back. If it measures 23 1/2 inches you have a small block flat 6 engine. If it measures 25 1/2 inches you have a long block engine. The long block engines are possibly Canadian or from a Crashler, Desoto, or possibly a Dodge Truck. The way to find out what engine you have is to post the engine serial number. This number can be found on a flat spot on the top or side of the front of the drivers side of the engine as pictured below. This number will positively identify your engine.

As before Thanks Don, don't know what I'd do without you.
I will check the serial number tonight when I get home. Is there a website that will tell me from the number what I have? or a book? if so what is it or where can I find one. Mine is the external bypass and it seems to be about 2 inches longer than the gasket I got from felpro so perhaps she has had transplant at some point. All speculation until I get that number and find out how to decipher it. Thanks and see you later.

OK Don here are the engine and body numbers engine: S8-952I3 body:22342S
I was looking at the picture of your blue one and it looks to be the same as mine, that is to say it has the external by pass and same configuration for everything as near as I can tell.

Your engine number S8-952I3 is not a Crashler number but a Desoto number for the year 1941. At some point in time a prior owner has installed a Desoto engine in your car. Did not come from the factory with this engine. This DeSoto engine is a long block engine. It left the factory with a bore of 3 3/8" and a stroke of 4 1/4" for a displacement of 228.1 cubic inches. Rated horse power was 105 @ 3600 RPM's. Source of this information is a 1953 MoTors Manual. If you bought a full gasket set for a short block engine the oil pan and valve cover gaskets will not work on your long block engine.
Are there any signs that the radiator in your car has been moved forward? Any signs that the front engine mounts where it bolts to the front cross member have been moved or new holes drilled?
The blue engine I pictured in my last post is a 1953 Desoto engine that I have installed in my 1948 Plymouth. I am not sure where you came up with the "341 Chrysler" information but Chrysler never made a 341 CI engine.

I mispoke, it is a 241 chrysler acording to the gent over at olson gasket who said that he has seen other 1950 dodges with the 241 chrysler motor in them.
You said it is a desoto motor. Weird, as it does not seem to have been molested in any way. the radiator seems to be in the original position, there are no unused holes in the firewall or drilled holes in the same, and from above anyhow the motor mounts look stock and all the rest looks like it has lived there since the 50's. Curious to know where you found that it is a desoto number. I believe it, as number seldom lie but that is weird. I really have to get some pictures of it soon and I'll post them as soon as I do. Thanks a million for all your help with this one.

P.S. I did get the right gasket and it is a fit for the 241 chrysler and the 228 desoto so no help there. Dammit. -

I would like to know where the gent at Olson Gasket got his information. I have never heard of a Crashler engine being installed in a Dodge at the factory.
Curious to know where you found that it is a desoto number.
The "S" in front of the engine serial number was only used on Desoto engines. Mopar used a "C" for Crashler, "P" for Plymouth, and "D" for Dodge. Any vintage MoTors manual will list this information.
P.S. I did get the right gasket and it is a fit for the 241 chrysler and the 228 desoto so no help there. Dammit.
Both the long block Crashler and long block Desoto engines used the same gaskets.
I would really like to see a picture of your car. Where are you located?
