Typically the Ford VIN was stamped on the engine. Many times the just the last sequential numbers of your VIN would be stamped on the rear of the driver head.  Less often seen is when it was stamped just below the head on the block pad cast for that purpose. There are also numerous possible derivatives of the VIN that could have been stamped as well . For example -140083 , 02R140083 ,0083 or any combination in between. I hope this answer the question you were asking because I wasn't exactly sure what you meant.

Sure I live in Australia and the person who did the restoration on the car, supplied a replacement motor because the car came with out the original engine.
He was going to stamp the correct # on the engine to match original.
There are other things to consider before wasting your time stamping numbers . There are assembly date codes when the short block was assembled and there are casting date codes on the block and heads. If the block was a later service block for instance it will have thick ribs protruding from the sides in the casting which are highly visible and tell the story that it is not a assemblyline block regardless of if you stamp numbers on the engine or not. If the date codes don't correspond closely before the car was built at Ford then there is no use stamping numbers on the engine because you will not make it look like a original engine if the other details are wrong.

Stamping of numbers is required in some countries for licensing and registration purposes. That may be the case here given what he has already disclosed

chrint is this the reason for your stamping or is it to make the car appear more original? If your stamping for registration purposes you might want it to not look original so your not going to mislead anyone else into thinking its original but instead it may be seen for what it is, just fulfilling state law

As for paint markings I think it's best if you start a new thread in the 69-70 section for that question. Keeps things easier for others to find information when they use the search and keeps things a bit more tidy that way ;)   Will need to know when the car was built and the body type

Thanks

9F02R140083 being the VIN number, your Mustang's original engine stamping would have been 9F140083. The year, plant code, and sequential VIN number were the components of the hidden VIN stampings found on engine and transmission.

Actually stamping this number on a replacement engine brings the question of ethics and legality into play as others have mentioned.

 I`m from Australia as well and as Jeff said you need a engine number for registration and insurance reasons , My CJ  came without it`s original engine also , so i just stamped 6 numbers (not my vin) on the front of My new CJ engine to satisfy law/transport department ,
