(1) Were the Protecto-Plates made at the assembly plant or the dealership. (2) When did the engine suffix get stamped on the Protecto-Plate, before or after the engine suffix was stamped on the engine pad. (3) How can I have an engine that was never stamped but has the engine suffix numbers on the Protecto-Plate? I have owned this Corvette since 1967 and it has the original engine. Many Thanks for your help.

Ronie,
Are you the original owner or did someone else briefly own the car before you?

Re: 1967 Protecto-Plate Questions
Aluminum stamped information on Protecto Plate was made on Addressograph/Multigraph machine at assy plant based on broadcast code (build sheet/tank sticker) information. The owner ID information was made at the dealership as factory had no idea who the original owner would be. 'GM' ghosted Dymo label tape was used at dealership to generate owner info, affixed to the Protecto Plate, the plate set into the warranty book's rear page and an emboss was made through credit card emboss machine onto TWO pages of the book using carbon paper. The original rear page was torn out and sent back to GM to record the warranty while the carbon copy page 'ORIGINAL OWNER" was left in the book.
Engine suffix was applied to pad at ENGINE assy factory (Flint or Tonawanda) along with the build date. Engine shipped to final assy plant where it sat waiting for host car to serve. Once this assignment was made, the VIN derrivative data was wacked by final assy plant on engine pad, engine was hung on assy sequence conveyor and took the ride to host car.
You can have an engine that was never stamped with suffix code to match your Protecto Plate in a number of ways -- none of them beneficial to you for factory concours judging. Engine could have been a legitimate 'oops' from Flint/Tonawanda, but in a '67 it's pretty rare as engine plants were then building in run sequences (lots of like kind) and the full ID code (plant, date, suffix) was gang stamped (all letters/numbers together in one fell swoop).
Car could have been an 'oops' item at final assy where it was pulled into repair pit and had its engine changed out. BUT, in most cases it would have been swapped with a 'fresh' engine pulled from stock with full engine plant ID code in place.
Engine could have been repaired by dealer prior to delivery or in warrany period using service spare components. Last, and a long shot, final assy plant was known to 'gather' component failures and group them until a critical mass existed, put technicians to work, and effect repair using as required parts vs. sending assy back to GM producing source plant.
In any respect, deviation(s) from NCRS standards for judging place the burden of proof on the owner to document the anomoly. Good luck!Comment

Re: 1967 Protecto-Plate Questions
Ronnie,
There is some more information that might shed some light on your vehicle. 1) What is the casting date of your engine block. It is located on the bell housing flange of the block just to the right of the distributor. 2) Is your car an A.O.Smith Body or St. Louis - body number on trim tag under glove box will start with either an A or S. 3) what is the trim tag date - upper left corner of trim tag. and 4) What was the approxinmate build date of your car. I can help you determine this information off line if you wish.
