Hi There to all you Mustang gurus 😉

Looking at buying a matching numbers 1972 Mustang Mach 1. Don’t know if the engine stamp is “legit” and need a keen eye from someone who has some past experience in viewing these numbers to give an opinion if possible whether this is an original 1972 stamp on the back of the engine block of a 351 Cleveland engine.

The black resin on the face of the numbers appears to be raised like it has been inserted and the numbers aren’t evenly laid out. The seller has been really decent in taking the photos for me which I’ve attached.
If anyone out there can help me on this it would be truly appreciated.
Much appreciated
Cheers

I'm no expert on Cleveland engine stampings, but those don't look like any factory markings that I have seen,
but then I haven't seen that many.
I'm into FE engines.

Sorry, not much help.

First check ALL the tags, engine, trans, diff, PS, carb, they all have a date. Then block, heads, intake part numbers. Buy the block (rear of the right Cyl bank) part number you'll see a casting date, heads, (inside the valve covers), even the intake manifold has a casting date. All should be before the build date on the door sticker.
These are 351W, but it shows what I mean.

This is not a Part or Built date Number, These Pictures are viewing the Flat portion on Back of the Block located on top, You can see the Top Trans Bellhousing which is bolted to the Block. That is the 6digit number of the consecutive Vin code.

This is the 15,156 vehicle built, but don't state:
1. Which plant it was built from
2. Want year this engine is built
3. Which Vehicle the engine is from
4. There is no indication this is a Cleveland

Pic "101420 - 1F248351" is the same Flat Casting as the 1st pic supplied.

One thing I am concern with is the STAMPING itself, It does match the character/Font style.

Mustang1972,
The stamping on the back top of the block looks normal to me. The vin should look like “2F” followed by your sequence number at the end of your VIN, so “2F115156”. In your case, the “2” is faint or only partial and the second “1” is actually stamped upside down. Very common mistake in my experience. The “F” is Dearborn in your VIN. The sloppy orientation is typical also. Good luck with your purchase.
