Depending on where you and your truck reside, a "possible" (no guarantee) way to determine if original rests on how the truck was titled.

Some where titled using the engine serial number (if your number matches the titled "number" in this case there is a possibility it's original, but not definitive as the engine could be a replacement and the title may have been updated to record the new serial number). Lots of years since it was built and potential for changes along the way.

If the truck was titled using the serial number from the cab ID plate, that won't help decide engine originality.

What you do know by the existing serial number decoding is the engine is "correct" for a 1953 216 that match your truck.

That's about as close as you can get to confirming it is original to the truck. Just the nature of the beast.
