Charley,

Curious as to the factory process that spared the stamp pad from the paint. And as a follow-on, why did they go to this trouble?

Thanks!

Charley,

After assembly ( and testing ) at the Tonawanda facility,
the engines were painted as they went down a paint line.
Accessories weren't added as of this time, so I would have
to think that the pad got painted. Shields ( vac-forms )
were used on the aluminum intakes to avoid overspray.
Possibly, the engine ID pad was oiled or masked in some way
to avoid paint. I would not think this to be the case though.

It seems to me that the way the pad would look as the car left the factory, would be a painted pad with the partial vin stamped right over the paint. I doubt there are any original examples still clean enough to really know though..

Steve,

Interesting thought. I'm actually not sure when the
stamping process happened. Obviously, the VIN addition
would happen somewhere close to the actual installation
of the engine in the chassis. The engine assembly code
would probably have happened at Tonawanda.

I have a factory photo of a small block engine being test run and it clearly shows the VIN pad as well as the end of the water pump snout (for the fan flange) and the lower radiator hose outlet as being bare steel.

I'm guessing JohnZ will know the answer

The pad was bare. They actually put a piece of masking tape over the pad when the engine was painted.
