Weird Hemi Block VIN Stamping

A friend has a purple 70 Hemi 'Cuda. It was not numbers matching when he got it. While watching eBay, his original block popped up and he was able to buy it back.

We were talking VIN stampings, and his looks a bit odd. Anyone ever see one like this with the "WT" by the vin?

doesn't look factory original

what is the MN426 number stamped under the starter ear?

It hard to tell with a 2 d picture but the pad looks milled to me. The fonts look wrong to me.

the W T is for Water Tested according to Repair Manuals Info . I also agree with block edge Milled , and Wrong Fonts . Hope He did Not pay a lot for that Block . Ronnie

Also...isn't the correct format 0B 194xxx no B0 194xxx ?

I thought W or WT should be on the top pad, not the rail pad; I haven't seen it in that location before.
That pad appears to have been milled twice.

That is how I would expect it to be .

The tell is does the car in question still have it's original transmission , if it does what does the VIN stamping on it look like ?

I have a 69 440 HP block that is stamped W T , it's on the top ID pad.

I have not seen a block like this either, but my knowledge is limited. Best to ask questions.
