1959 a110 engine

I’m having a hard time finding out which engine my truck has. I can only find the IH stamp on the front of the engine.

Any info?

Is the small 6 the engine number should start with the family, (SD BD or BG) followed by the displacement and the serial number. These will be STAMPED not cast into the block on the pad provided.
I am not a expert on the small 6 but unless I am mistaken, the pad is on the right side (passenger in the US) on the BLOCK (not head) between #1 and #2 cyl.

CB, I am helping Joe out with this effort. Since 99% of my knowledge and experience is with the K line or the IHC tractors, I sent him here, as there is a wealth of knowledge and help. I am digging into which engine he has. Here is what I can tell you:

it does NOT have the triple diamond cast into the block to the lower right of the distributor
it DOES have the stylized IH cast into the front lower corner of the block to the left of the oil filter base on the distributor side.

I have found the fuel pump and rebuilt kit for the Rochester B carb that is on it. Engine runs great, but the carb seeps gas like a screen door. No smoke, no knocks, and it appears to have been rebuilt at one point in time.

Right now, the documentation that I have found so far, indicates that this came from the factory with the BD264 and a Holley carb. Now, that is NOT from IH documentation, but rather a carb/engine truck model cross over sheet. Again, I am finding it difficult to narrow down the external differences between the black and silver diamond engines and truly pin down what the factory options were on this old girl.

The other thing I have uncovered is that the main difference between a 220, 240, or 264 is the stroke. Bore size is all the same. Blocks are very similar as well. This puppy seems to be a whole different animal than the K-line and the GRD engines.

Lastly, I find it highly interesting that the carb linkage actually runs through the block. Frankly, I have never seen that type of setup before, but there are lots of things in this world I have yet to see and learn about.

More to come as I dig deeper into this.

As I stated before, I'm not expert on these blocks. The engine number will tell the story, so search the block for the pad and stamping. I believe that is a tilt valve engine, and can't say anything beyond that as all in that engine family look the same externally. The biggest may have a 2bbl or may not. So may be a 240 or 241 or smaller.
I don't believe IHC ever used a Rochester but a carb is just that, they all do the same job, and within reason any carb can be adapted to any engine as long as the CFM's are close to what the engine need (not way too big or way too small)

Thanks CB and Kevin. Joe is coming over this afternoon, and we are going to try to get the brakes working. I'll check out that location on the block and see what is stamped on it.

Looks like a tilt valve here is a link for some specs

Not that it matters now, since you know the engine size, but the 264/265 has a 1/8" larger bore as well as a longer stroke compared to a 240.

Dean, yup, you are right. I went back and looked closer at the scanned manual. I have "old man's disease". I saw the larger bore size on the 264 as well as the stroke. Need to use my glasses more often! Thank you for the correction.
