The Serial Number is for a 1954 Chrysler Windsor which engine was made in the Windsor Ontario Engine Plant and the car came from the Windsor Assembly plant. It was a 265 ci motor when it left the factory .    3 7/16" bore and 4 3/4" stroke   That being said the serial as 55 Fargo point out on another one, was not applied at the factory.  The factory used a jig which held all numbers,  letters and any special character together so when the serial number was applied they were absolutely in a straight line.  This is a restamped block.   1954 was the 1st year the Windsor had a v8 in it, although at least in Canada the 265 was an option.

 

 

 

 

The part number that is cast into the block -1400229-1  was actual a part number used for the 238, 250 and 265 ci engines and was a block number casted from oct 1951 until 1955 actually.   If you looked inside the block you would notice its been carved on the side which allows for the long stroke 265 crank and rods to have clearance. That same carving was

done in advance of it being known which ci motor it would be.

 

If you look closer to the oil filler tube, but down by the oil pan you will likely see a Letter (likely a D  and then a number (1 or 2 digets) and then another number (1 or 2 digets) .

That will allow us to figure out when the block was casted.

 

You can also look up a little higher and see a clock face cast in the block and a code for what shift it was casted on.    The USA engines are a lot easier to determine the 

casting date that the later Canadian 25 1/2" engines,  but thats a long story that really doesnt help in this discussion

 

 

 

Good eye... 55 Fargo your 100% correct.  while the t137 is an excellent resource it really is, it is not without its gaps and Canadian engines are often part of that gap.

 

A classic example would be looking at a 1949 Plymouth you will see a p18 shown as a 218.   Without getting into a big debate,  it really was known within Chrysler as a 217. The Canadian 25 1/2" engine was a 218.   However the real point is  I have a 1949 Plymouth that my great aunt bought brand new.  Its a p18 serial number.    It was neither a 217 or 218... In canada they were 228 ci 25 1/2" blocks.   On the t137 site it would show the 1954 chrysler 6 cylinder as c62 and that is correct...    Correct for engines which were shipped to the USA for assembly into a 1954 Chrysler.   For engines that were going to the Canadian assembly plant in Windsor, they were marked c54.    

 

Hope that helps

Great info Tim.  A couple years ago I called you and you helped me determine the details of my 1954 265 engine. Thank you! Great wealth of detailed knowledge.

 

It has since then been rebuilt, have a AOK triple with split exhaust.  I havent started the motor but will soon.

I purchased the engine and transmission with a rebuilt carter carb and rebuilt distributor for $100 about 2 years ago. I saw a local add for two complete 1954 Windsors with 265’s for $500 for both.

If I had the room I would have 2 265 engines sitting around.

 

havent found many since and when i do, they want up to $3-4k for them
