I'm confused [easily done these days! ] I thought engines arrived from Flint/Tonawanda as already painted long motors, as per pic in assembly process report?
Or this this thread specific to z28?
X2 What he said and if they were painted that means they were stamped as per other thread.
Funny you should mention the stamping thread, it was my reading of that one which got me wondering exactly what happened when, which has led me back to this thread!
However, regarding the stamping thread, perhaps John was meaning that the engine code
was stamped long before painting, perhaps before assembly of the block even began.
After the long motor was assembled, the pad was masked and the motor painted - off it goes to Chevrolet.
The partial vin was then stamped at the start of the Chevrolet engine dress line to an already painted engine, with no paint on the pad.
But I surmise, we need John to guide us to the light.
