I have found a castig number on the belll housing of my Engine. K841. Does the 41 stand for the year of the engine. If not can someone help in helping with the year. Thanks Howard

To me there is only one known way to assembly date code an engine.
Keep in mind that not all engines had a date code.

My understanding is those casting numbers don't tell you anything. The 41 you see does not indicate the year block was cast.
This is from VanPelt's web site:
"The foundry would also place what were probably "lot" or "production" numbers in the castings on all blocks. These were usually a small group of letters and numbers cast on the top of the bell housing....right next to the vertical surface of the back of the block. Unfortunately, any records of these numbers are long gone and they provide no clues as to the particulars of any engines."

I don't remember every seeing an engine block with those date codes stamped.
Today it is more typical to see a replacement engine than a 100% stock original engine in a flathead era Ford. This is due to Ford's practice of offering exactly that service, which was copied by aftermarket firms.
To identify the engine block please check out the big thread we did on the subject a while back:
