The "Corvette" guys mastered the art of rebroaching (the complete top of the block if need be)stamping/and even aging the stampings, a long time ago.

Stefano,

If that is true, then why does the NCRS make such a big
deal about broach marks? It's often a topic of discussion
there.....

Stated another way, if the broach marks & stampings can
be "cloned" easily enough, why do they make such a fuss?

The broach marks can be reproduced, and the engine can be restamped.
However there is a large database of numbers from almost EVERY SINGLE day of production.
Still hard to fool the experts with access to that knowlege.
IMO the repro stuff always looks too perfect.

Here is a well known pad "recreation", that looks very good.

I thaught that even if the deck was restamped, broached and looked perfect- a deck height measurement would give it away as a redecked block? True?
