512 MN Block - Legit or Re-stamp

[talwell]

This block is listed on eBay as a legitimate "MN" block. The stamping appears rather deep but fairly legit to me but I am not an expert.

I would like to hear opinions on this one.

I can't see from the picture but the pad is pretty pitted so much that the broach marks are gone. Look into the depressed areas of the stamp to see if the pitting is also present, If not I'd be suspect.

If it is a true MN block, shouldn't it have a vin by the oil filter?

What would it have been installed in? The very first Yenkos have much later engine dates. This would be the earliest MN engine by a wide margin.

I think it's fake. The numbers and letters aren't even close to the picture I have of a real MN block. Compare the &quot;T&quot;, &quot;0&quot; and especially the &quot;M&quot;. They are also too straight and too deep plus as Rich stated, the broach marks suck. <<GRAEMLIN_URL>>/thumbsdown.gif

I emailed him for the VIN and the reply was 19N56737?

According to a site I just looked at the first 427 Camaro VIN was 578xxx. <<GRAEMLIN_URL>>/dunno.gif

Not sure if it means anything but all the blocks he is selling seem to have pitting on the pad with uneffected stampings except a 70 396 block he has for sale. The VIN stamp on the DZ block looks very suspect.

In your known good &quot;MN&quot; block I notice that the &quot;0&quot; has straight sides with only the top and bottom edges being rounded off. In the eBay one, the entire number is rounded.
As well, all the fonts appear just a little off without even considering the VIN date issue.

The center peak of the letter M on the ebay block comes all the way to the bottom. The center peak on the letter M on 69PostSedans's block doesn't.

Waaay deep and strange font, throws a red flag!

[Mr70]

I agree on all accounts..looks homemade to me.

STAY AWAY!!!!!!

[talwell]

Either someone thinks that they can pass that off for a huge pay day to some uneducated buyer or they dont realize that anyone that even knows what the &quot;MN&quot; block is will certainly validate it before buying. Now they have a 512 block that needs to be decked to get rid of that bogus stamping.

Thanks for all the images for comparison - once again the yenko.net community proves thier knowledge and abilities.

[Pulnaway]

as deep as that is stamped i dont think that is going to go away even after decking.

[YENKO DEUCE REGISTRY]

Too deep to deck away.... Bummer, could have been a good replacement piece if left alone, <<GRAEMLIN_URL>>/frown.gif

The engine plant had several different suppliers of those stamps. When they changed the dates, the fonts would change so you can't really compare a Dec block to a June block.
Restamp, btw. <<GRAEMLIN_URL>>/smile.gif
