to me, the depth, boldness and uniformity of the numbers look to "mechanical" for me. The other pic shows numbers where it appears that the gang holder was tilted at an angle thus the upper parts of the numbers/letters are deeper than the bottom, indicating that it was apparently done by a human.

If it is suspect, the first thing you look for is the height of the deck vs the waterpump. The deck is always higher. If its not, its likely to have been ground and restamped.

Not true in a big block.

There are just too many variables. I've seen motors with almost no broach marks and some with very heavy ones. New cutters vs. worn ones. Stamping variables - new stamps vs. old ones, heavy hit vs. light one, tilted holder vs. one held square, guy doing the stamping that gave a **** vs. one that didn't and on and on and on. And then throw in 50 years of exposure to all kinds of environments.

Well stated Jim Some things give you clues and some are just not correct but there were all kinds of variables coming from the factory so it is not just one WAY

Broach marks look like broach marks. No other process I'm aware of looks like broach marks, whether they be light or heavy.

Whether the "guy gave a ****" is irrelavant to the appearance of the stamp. Most SB stamps are light on the forward, right side, heavy on the left rear side for a good reason, and it had nothing to do with whether or not the "guy gave a ****" The depth of the stamp, for the same reason. If you'd ever been in an assembly plant, you'd have a better understanding of the process.

FYI, the serial number stamp was considered more or less a PIA back then even though it was a required process and later on, Uncle Sam mandatory compliance.

If you see a really weathered pad that you're not sure of but looks "ify", buy it.

It's much easier to determine what is NOT RIGHT than what is right.

The best thing to do when you buy is too ignore the pad and buy the car for what it is worth. The engine is the cheapest thing to make "right". Then you don't have to play these stupid games.

Well I guess everyone is entitled to their opinions. I'm glad you're an expert on what expirience I have.
FYI - I've been studing VIN stampings prior to "uncle sam" requiring it. In fact, I have many pictures of blocks that were stamped before a gang holder was used and to say that the quality of stamp has nothing to do with the person doing it is total B.S.

I agree. There is also "alot" of variance in water pump castings. Alot.

I don't speak from opinions. I was there for a number of years.

I've never heard of an engine stamp done in an asembly plant unless it was done with a gang stamp. You ain't got time to do it individually to start with. If it was done without the gang stamp, it must have been many years ago and not applicable to current discussion.

You are totally out of touch with reality.

And like I said, the person doing it had "other" influencing, outside factors. Get real!

In 1960 when they started stamping the VIN and they were done without a gang holder. You should have known that since you were there.
After following your dumb azz replies in the "spindle thread", I'm not going to get in a childish pizzin' match with you. I'll just admit right now that you know more than anyone who's ever walked the planet and have never been wrong in your life. No matter how much evidence there is to prove you wrong.

We're not talking about 1960. Pay attention.

With your attitude, it's probably a good thing you're living over there in a corner of the country where you don't have too many neighbors to bother.

And your post(s) is/are irrelevant to this subject. As are you.

You seem to be a man that likes the last word. Go ahead.

That statement shows what a baffoon you are. There are several million people that live in the Puget Sound area. You really should stop posting so people only think you're an idiot instead of proving it. I'm done.

Puget Sound? Where is that?

"Baffoon" is spelled "buffoon". I was here when you got here and I'll be here when you're gone.

I have to laugh....

Some poor puke on the Corvette assembly line could never have imagined at the time two guys flaming each other in cyberspace, 50 years later, about how he was doing his sucky job.

The second sample with the head removed, says honest to me. That textured look for now is impossible to replicate with a file or belt sander.

Lazer etching is not far off, but for now if you see that honest look its probably orginal.
