Default Engine Vin Missing S Plant Code

I have a 78 Pace Car which on the engine pad has the engine code and the 18 and the last 6 of the vin but no S for the plant between the 18 and the last 6 of the vin.Did anyone ever see that?

No. Does the stamp on the transmission also have a missing S?

Please see the attached picture, it is hard to see. The Engine Code as follows; V0407 which in line of the build date of the car. CUT; 1978 350 a/t L48 185. The vin stamp has the 18 then a space and then the last 6 of the vin.

Thanks

Mistakes on engine pad stamps (and other stamps as well) are not that rare.

They did not happen every day, but they occurred often enough that we have come to expect / accept them.

The rest of your pad looks fine.

I would not worry about it.

But, check the VIN derivative stamp on the transmission and see what it looks like.

Thank You,

The trans is fine, I also check out the following part number and date code; carb, alt, master cylinder, starter, distributor, wires are dated coded 1st qtr 78, and diff all is correct. I also have a ton of documentation that came along with the car.

When you say "The trans is fine", what exactly does that mean. What does the VIN stamp on the transmission look like?

Engine, trans and frame stamped with same stamp by same guy at the same time. So they SHOULD look the same.

It's also possible that the S in the gang stamp came out really light and just isn't visible in the pic. It might actually be there and probably is.

I am going try to look closer, everything else is correct and even having the 18 space and the correct vin. The paint on the engine is also original.
Thanks

Thanks

The same gang stamp was used for engine and trans. If the S is in the tranny stamp, it should also be in the engine stamp. That said, stranger things have happened.

I wonder what the engine pad would look like with the paint cleaned off of it.

There looks like a space between the '8' and the '9' where the 'S' would be

I agree, with the space there I felt the stamp broke or was wore out.
I am going to try to clean up better see if I could see anything.

Thanks all,

[QUOTE]I only see five characters for the consecutive unit number (looks like 90391 in the pic). There should be six characters.

There is 6 the last digit is very light but if you look close in the picture you could see the seven.

Yep. I deleted my post after I saw what looked like the 6th character.
