Farmall 100 - s/n on engine block

Does anyone know the significance of the serial number on the right front of the engine block ?

Cast Numbers : C-123
Block Number : C 354898 R3 5.1.?? L
S/N ? : 33341

As the story seems to unfold, Papa bought it 2nd hand, but in the early 60's. Been in the family ever since.

According to Brother-In-Law, this 100 would plow circles around their Super A. It would catch up to the SA in one round, and three or four rounds later, pass it up again !

Well, now that I've had the engine truely overhauled, the plot thickens -- it took a 130 kit to overhaul, due to the larger outside diameter of the cylinder liners.

Also, the 5.1. ?? casting, what does it siginfy. Does the unreadable 2 digits represent the Year ?
 
C is for gas, 123 is cu. in., 354898R3 is the block part number, there is no C in front of it. The 5*1* should be followed by the letter Z, A, or B, as the 100 was make in 1954,55,56. L means it was cast in Louisville Kentucky, which is also where it was assembled. I don't believe that 33341 matches any of the engine serials for the C123 installed in the 100. Hugh MacKay or someone will correct me if I am wrong.
 
Super A's up to about 52 or 53 had a C113 engine, that would explain the power difference. Lots of Super A's older than that.
 
couv: If the block part number is 354898 R3 a 130 rebuild kit will not fit. 130 has block number 366204 R1 and that kit will not fit block 354898 R1, R2 or R3. Either someone is pulling your leg or you had a parts guy that didn't know much more about it than you do. The 354898 R1, R2 and R3 were used in SA, SC, SA1, 100 and 200. There was 3" bore, 3-1/8" bore and 3-1/4" bore kits for that block, and I suspect if it was that much power over your cousins SA plowing the 100 had 3-1/4" bore and SA had 3" bore. You will not get that much different between factory SA and a factory 100.

Block number 366204 R1 can only be equipped with 3-1/8" bore kit.
 
Now would not a bored C-123 to 3 1/4 have some sort of power advantage to a C-123 3 1/8 inch bore. or a C113. Not sure what you are saying.
 
Rich: I'm certainly not sure what you are saying. Yes, these blocks can all be bored, however I question how many have ever been done. Block number 354898 R1, R2 or R3 used in SA after serial number 310300, and all SC, 100 and 200 is already bored for for 3-1/4" sleeves. The 3" and 3-1/8" kits for that block just use thicker sleeves. No point in boring that one, there is nothing larger to fit. As for the rest, one can probably buy a 354898 block for a fraction of the cost of boring.

Block numbers 366204 R1 and 367825 R1 and R2 each have one size sleeve, that being 3-1/8". Neither of those blocks are bored as large as block number 354898 R1, R2 or R3. Block 366204 R1 was used in 130 and 230. Block 367825 R1 and R2 were used in 140 and 240.

While boring is possible, it's not very practical from a cost point of view. Used blocks are just too plentiful.

CNKS: couv has just posted a photo of the engine serial number. 100 and 200 tractors used a common sequence of engine serial numbers. Records I have show the first engine used in 130 was 36046 and 230 was 36001. He does have the right engine for a 100.

The last engine used in a 100 was tractor 18940 and engine 35930 and 200 was tractor number 15698 with engine 35131.
