March - June 1967 Tonawanda stamps - 3
 

Does anyone here who collects pics of real factory Tonawanda big block stamps have any examples in the March - June 1967 timeframe with a round-topped 3 in the Tonawanda assembly stamp? All my examples (hundreds) have the flat-topped 3.

Looking at a car that everything looks pretty legit on, except a round-topped 3. I have one stamp the very same day with a flat topped 3, but it is a different suffix.

Pretty confident it has to be a restamp, but thought I would ask here before putting the final nail in the lid.

Feel free to PM me if you prefer versus posting any pics on the public forum.

Thanks!

Jeff,

I have a January stamp if that is of any help (with a 3). I also have a May stamp (but no 3)

What type of car was the engine going into?

Thanks. Flat topped 3 like all my examples.

The one I am looking at is a Chevelle. But that would not matter on the font of the 3 used at the Tonawanda engine plant for the engine assembly date.

They had a number of different fonts to choose from. I’ve seen unusual numbers show up as one off examples. It would be best to find a an assembly with same date and build code that is legitimate for comparison. The next best is to find one that is close to the same date with the same application.

Three March and one June here, all flat top 3.

Loads of pics here on now of Dale’s pages but all 3’s from Tonawanda are flat tops:

Jeff, I just now removed the paint from my block to get a more clear picture of my stamps. The 3 in my vin stamp is a round top 3. As you can see the block is the last week of May stamp. Cars TT is 06A.

Thanks very much! I am only concerned in this particular case about the Tonawanda engine assembly stamp.

VIN stamp fonts depend on the assembly plant of the car that the engine was installed in, and the time frame during which that VIN was stamped at that assembly plant.

By contrast, Tonawanda engine assembly stamps were all done at Tonawanda, regardless of where the engine would end up getting installed in a car. So they "should" (with some documented exceptions) be all the same fonts on big blocks built within the same time frame.

I was sort of hoping that I had somehow missed a batch of round-topped 3's from Tonawanda during this time frame, because I really like the car this engine is in! But so far none have surfaced (here or in PM or in some other avenues I have been searching).

Thanks to everyone for the help!
