"h'beams"....Please allow me to help you fully understand just a little bit mo-better about engine numbers, frame numbers & trans/bellhousing numbers.
Way back in the day....up through the 1931 Model "A", Ford actually did stamp the "Motor Number" on a smooth, blank pad that was cast on the drivers' side of the 4-cylinder blocks. When that engine/trans combination was lowered into a chassis on the assembly line, the chassis was also hand stamped with the SAME number stamped on the engine. On a Model A, that MOTOR Number was the easiest to see and be read on that engine pad, as the numbers stamped into the frame (on a Model A) cannot be seen without raising the body. Today, since many Model A engines have been swapped and replaced, it has become difficult to verify TITLE numbers without lifting the body from frame.
Now in 1932-1948, Ford began stamping sequential "Motor/Engine Numbers" (as they were STILL referred-to) on the transmission clutch housing pad at the time the transmission was bolted to the engine, creating a MOTOR/TRANS assembly. The term "Motor Number" was likely just carry-over from the Model A days as what it was referred-to in written manuals. That V8 engine/transmission assembly with stamped "Motor Number" on the trans pad was stored with thousands of other like assemblies, until they were shipped to automobile assembly plants all across the US. When each motor/trans assembly was lowered into a new chassis on the assembly line, the SAME "Motor Number" that was stamped into the trans pad in the engine assembly plant is now hand-stamped into the frame rail in the three usual locations. Clearly, the Motor Number (on transmission) has EVERYTHING to do with the three numbers located on the frame. Also note that it is much easier to verify the "Motor Number" stamped into the FRONT location of a frame rail, rather than having to remove the carpet/mat/padding material which is necessary to read the MOTOR Number on a '32-'48 transmission pad.
