i decided to check the numbers on my 70 340 block should someone be looking for this particular block for a matching numbers car Is there anyway to tell if this from an A or E Body? I bought it from a guy in Illinois IIRC

It is from a Duster- VS29H0B429494

You asked about it in May of 2015 too. ;-)
 
Ha!

I run the 1970 Hamtramck Registry, so I take notes.

If I hear of the car I like to have a record of who reported the block so I can tell the car owner about it.
 
Just out of curiosity how can you tell it came out of a Duster by a partial VIN Number? If you can enlighten me, Gives me an opportunity to learn something new today since the memory from 2015 is slipping lol!
 
Most plants assigned VIN numbers in body type 'series', so the 1970 Valiants & Dusters would be in a series, Barracudas / Cudas in another series & Challengers in their own series too.

So if I have a series on file & a block or transmission hits withing that series I can answer questions like yours.

When the cars were actually made though, they were all mixed up on the lines & built out of VIN order all the time.
 
VIN is just a number assigned when it is being scheduled for build...

Sequence number is on the build sheet.... Sequence number is what actually determines what order it went down the assembly line...

Very rarely are two consecutive VIN numbers built back to back....


When a vehicle is ordered, it gets assigned a VON (Vehicle Order Number)... This is what they use to track the order through the system until it gets assigned a VIN....

Then it must pass edit where they check all the sales codes to make sure that they are all correct and can be built together (no conflicts).... If it fails edit, the order is kicked back to the dealer to be corrected...

If the order passes edit, then it is assigned a VIN and then it goes into a 'pool' waiting to be scheduled....

When it gets to the front of the pool, it gets assigned a sequence number to go down the assembly line which determines which order it is built....

VON numbers are in increments of ten usually, in case they have to slip one in, then assign it a 5 or other last digit.... That way, it's easier to shuffle one or two in when the occasion arises....

The letter in the 7th to last position is the assembly plant code...

If you know what assembly plants built which car then you can figure out what car it was originally in....
 
Thanks to both of you guys for the explanations- I appreciate it!

Great information here.
A question for you is if the cars have sequential serial numbers and you don't have a build sheet for either but you have a fender tag for both, can you determine if they were indeed built back to back?
The cars in question are both '69 Coronets, one a 2 door and one a 4 door in different colors, options, etc.
I do own both cars and sadly they are just parts cars.
Interesting nonetheless................
 
There is no way to know how close the actual builds were for most cars.

The Hamtramck plant (1969 to ? ) is the only one that issued sequential build numbers, so they can indicate where those builds started IF you have a broadcast sheet, but that number will not indicate the order they finished in.

I don't think that the assembly plant sequence number is coded on the fender tag...

They are on the broadcast sheets/build sheets that you usually find under a seat or behind the glove box.... There is a space on the build sheet that lists the assembly plant sequence number...

The car gets loaded to the assembly line in sequence with the assembly plant sequence number...

However, it can be mixed in the paint shop... Two tone paint takes a second pass through the paint shop for the second color vs a single monotone paint which can be done in one "lap" through the paint shop....

If there was a paint or dent repair, then they go through another loop instead of straight out to the assembly side of the plant...

I guess the fender tag shows the order number and options, but not a lot else other than order number and the V.I.N. then.
So, without a broadcast sheet, you can't tell if the cars were actually built back to back, right?
 
Not sure if that can be done for the plants that made 1969 Coronets. It would be cool to see a photo of both tags together though.

Most likely...
