I saw this block also.  Is it a real DZ ?  Curious why some D's stamped are more rounded looking while others appear to have flat looking bottoms.  I'm searching for an original DZ for my 05C (May 13-22 ... guessing)  Would this be a few weeks to early ?  And is this about the going price?

anyone's opinion.... much appreciated

Thanks

I compared my stamping to that one, and most of the characters in my stamp are 'wider'...?   the D is more square in mine, as is the 'zero' and the '2'...  I've no idea if that means this one is a restamp, or if different stamps were used at various time, or even simultaneously?   My engine is a late August 69 engine..

Block looks good to me.  It would be better if the car owner new that his original block was still out there.  I.E. the reason for Kurt posting this.

Thanks Ed...  If I ever knew that, it was lost in the dark recesses of my mind....  Smiley    So what this means (re font style) is that you'd need two engines made on the same day same plant and same suffix code to compare any potential differences in font.

Re the engine under discussion the location of the stamp looked good, but photo detail wasn't sufficient (for me) to see broach marks.   John's statement on how the factory set up the gang stamps makes the existence of original broach marks much more important in determining originality of a stamping.

To add to that, there was more than one line assembling engines (with each line having their own stamps), so you would need to find another engine built at the same plant, on the same day, on the same line! (Which is why the CRG needs - and has - such a large database of engine stamp examples!!)

And yes, broach marks are extremely important when looking at the numbers.

Broaches wear and thus the changes due to wearing will show in the marks the tooling produces in processing the work piece. If you have broach marks from day to day they would show a progression of wear in the "scratches" produced.
