1972 Engine Code stamp - authentic?

[David D.]

Wondering of any of the experts out there could evaluate this engine code stamping on a 1972 LT1. See first attachment. I don't think these are typical broach marks, and the "1" in the engine code stamp looks like a lower case "L."
The second attachment is from what is believed to be an original 1972 base engine, and the "1" is a different font.

Thanks in advance for any assistance you may be able to provide.

I am less thrilled than you are with the supposed originality of the second pad. A closer shot would be better, but the alignment of the letters certainly looks ntfp.

Mike - thanks for your reply. Unfortunately, I do not have any higher resolution photos. What do you think about the "1" font in the LT1 stamp? Was this ever typical?

It's not uncommon for the number "1" to be stamped as a lower case "l".

I've seen many like this and the judging guide even states this.

Others more qualified can comment about the other features of the pad and stamping.

It's not just the I, but the distance of the I to the C appears too close.
The resolution is not good enough to determine how good the broach marks are compared to factory.

The 72 base engine is certainly original, but I have never seen a straight vertical line used as a "1" as in the LT-1. The broach marks are also suspect. I would bet against it.

Patrick,
Please explain to me how you can say the 72 block stamping is "certainly original"?
Thanks,
Mike

The 2 and the 3 are distinctive characters that are typically found on early 70's Flint engines. The vin characters that are visible look good, and the grain looks good.

I'm not trying to be difficult. I am familiar with the 2 and 3 in that time period. Also conversant with broach marks. Also aware of professional restampers with original broach machine and correct 2s and 3s. I'm trying to understand how anyone can say "certainly original". I can understand TFP, or "appears correct"

It's my opinion and worth every cent. I understand the opinions you actually pay for come without any explanation at all.

The last 4 digits of the engine stamp in the first pic sum it up nicely...

I've posted some 1972 LT1 stamps before. I'd be more suspect of CKY stamps that actually were straight and in a uniform distance from the date.

I agree - that's funny.
