The engine in my 41 Deluxe coupe has the number 59 on the bell housing signifying it's a later block. (46-48). What does D21544 signify?

The numbers are casting numbers from the mold the block came from. My number is J3611

Ford did not use any numbers on their engines that have a connection to being serial numbers, etc. The number 59 cast into the bell housing denotes that the engine is a '42-48 239 CID which is a Merc engine. Generally speaking it is the most common type of replacement engine that Ford used. If there is a number stamped into the trans bell near where it mates up to the block, that would be the original serial number for the car that the trans came in. As a general rule this number was ground off of the transmissions if the unit was sent in as a core for a rebuilt trans. It is pretty well common knowledge that the majority of the vehicles that had a transmission replaced did not get the correct Serial number stamped back into the trans case. As a point of info the serial number was assigned to the engine when the engine was assembled and the two units attached together at the Dearborn plant. When the engine assembly was installed into the chassis at the respective plant, the number was stamped into the frame in an area adjacent to the steering gears

Thank you, I still have the original trans. as i have rebuilt it twice after 60,000 miles. Now looking for an 81-A or 81 AB engine. Is this correct or even obtainable?

On the top of the transmission housing near the little inspection door you should find the serial number *18-serial number-* For a 41 Ford the number will be between 5896295 and 6769035. You should also find (hopefully) the same serial number on the top of the left frame rail somewhere between the front cross member and the firewall. If looking for it on the frame be gentle, the number is easily erased by aggressive brushing, grinding ,scr*ping ,or sanding.

If you are looking for the correct engine block for your 41 Ford, it would be one that has a slightly raised deck for the intake manifold. Only the intake platform is machined, the rest of the top of the block is just as it came out of the casting mold. See attached photo from the internet

Do not look for the 81A number on the 1941 block. The 81A was used from 38-40.

The drawing that I attached to my previous post contains all of the information that you will need to obtain a correct 1941 block. There doesn't seem to be any records of what the casting numbers mean and all blocks did not have them.

What years were cylinder sleeves used? And what was the reasoning? Simple forward thinking for longevity/maintenance? Thanks!
