'69 Z - Block Stampings?
« on: March 07, 2020, 04:49:54 AM »
How do these engine stamps look?  Claims the block has been lightly decked...

The heads are not original as they started out life as small valve heads.  The combustion chamber has not been unshrouded as it would have to be if they were original big valve heads.  Valve covers are reproductions.  Bob does know these things but he fails to mention it.  I am not surprised.

Difficult to say much about a fresh decked block.  Can not be proven either way now.  Bob would have taken a picture of it before decking if it was in his hands at the time.  He did not post a picture of that so he does not have one.  It will forever be in question. 

Looks like a real Z/28 to me from what I can see there.   That is a lot of money for a project.

I noticed that the heads are converted 1.94/1.50 heads too, the thicker area between the intake valves is a giveaway because of no chamber machining around int valves. Good eye Stingr69. FWIW That block is not freshly decked IMO, looks like very old machine marks, there are things about the stamp that are not normal also I think.

JMO, but I can lend a little support for the decked block - looks like the milling pass was light, some removal above the numbers (especially the 3) caused them to appear shallow, sharp faced stamps, plus the different fonts have been seen before (replaced in the set due to wear, breakage, loss). I wouldn't count it out -

The Vin stamp on the trans and the engine have different individual stamps trans has flat top 3's and the engine has round top 3's and the 2 is not the same at first glance... not saying it's not original HOWEVER - it should be checked.

Thanks James.

If the trans stamp vin and block vin are different characters then I suspect 1 of them is a restamp. Apparently the block & trans vins were done at the same time with the same loaded gang holder and characters so how could they be different? The trans stamps certainly look original?

As far as the Flint block build stamp characters, I have seen different fonts before but I’m guessing its not the norm, I think it has other issues too.

Anybody have any pictures from the same month to compare ?

Here's mine, March dates, but LA built.   Trans and Engine VIN stamps are identical.  Round "3's"

It is not unusual for Norwood engine/trans VIN stampings to differ.

Learning more and more about less and less...

Thanks William ,

 So Norwood workers could have used 2 different holders with different characters\ fonts?

They did use different stampers, probably done at different points during final assembly.

Yes, we sometimes see the different fonts and we don't know why. These VINs would have been stamped on the engine dress line. I was involved in engine dress lines in several plants and I surprised that two different stampers were sometimes used...

Most known original Flint stamps are higher on the pad towards the Intake flange, this Ebay stamp appears like it is centered on the pad that's why I was questioning it. I know they were applied by workers but did this occur more?
