Default engine stamp experts please

Usually I can make out broach marks but in these pictures the paint and age may be getting in the way. Do the numbers look legit to you guys?

Yes they look typical of factory production. Is it an original pad or a restamp? Dunno.

I can't... the car is about 800 miles away. I'm thinking hard about going to see it along with another.

Don't mean to hijack the thread, and I'm sure your numbers are legit, but why are there 2 number "4" 's and 2 letter "I" 's on your car's pad? ( on the plant side w/ date and suffix code)

Asked that of all the NCRS gooo roos double strikes also known as "BOUNCE" were very common, as they were done by hand with a very heavy hammer......
Size, shape, angle, location, broach marks are all consistant with being "CORRECT"
LOOK CLOSE.........COMPLETE DOUBLE ...........BUT VERY FAINT IN PARTS

I agree that the pad is original. I am aware of the bounce effect.

But also think of it this way. If someone were going to re stamp a pad with an illigimate number I do not think they would allow any apperance of the old numbers. They would make sure that all of the old number was 100% removed. So in a odd way in my mind a double stamp is additional proof of an original pad.

An original pad stamping, but with the surface rust, I doubt that you would ever be able to see the factory broach marks any longer.

My first observation was that those are some nice broach marks...had to do a double take to catch the double strikes.

If you look at the 'bounce' the same numbers/letters that are more defined in the first strike are also more defined in 'bounce' strike and the fonts are identical. Looks good!!!!!

I saw you post these same pics in a "numbers matching" thread before. Your car is certainly beautiful and I believe that your engine stamping is authentic. However, if this is the best example you can supply of a re-stamped block then you obviously haven't seen very many or don't have on file very many pics of re-stamps. The biggest difference between a quality re-stamp and an authentic one is the new shiney metal produced by the decking process. I suppose a person could replicate the aging process with a little water, grease and dirt. And yes the holy broach marks are replicated as well.

Hooray... I got my post back!

Alan, I can't say... I only have the picture and will go see the car soon. My guess would be grease did not allow it to stick or it was brushed on (doubtful). I really doubt any funny business on this one but without the clear broach marks I am getting familiar with I thought it might be interesting to hear some opinions.

Thank you for the reply. I'm trying to schedule this one and will report back in a new post entitled: "I just bought my first Vette" or "I'm still looking".

If you look close at the vin I can see a 0 bounce below the 0 in your picture. Check it out when you look at it in person.
