looking for info T/A and AAR built end of march beginning of April, found several in that time period built within 2 days of each other and another 7 days apart Door vin 3-70 fender tag dates 401 ,403, 407. all motors no vin #'s all cast same date . anybody else have a T/A or AAR built in that time slot with similar scenario. or any info. I know its only three cars, but find hard to believe that they are all warrantee blocks. does anybody have any accurate info?

There is no way to know how many days apart these cars were actually built.

The date on the tags & broadcast sheets is actually the Scheduled Production Date, or SPD. It is the date that they hoped to build the car, not a 'build' date set in stone.

The original door stickers on the other hand were required to indicate the actual final build month & year. This is why the dates on the stickers do not always agree with the SPDs.

Lots of folks assume that the cars were built in VIN order, but it did not happen that way.

Also......

Warranty blocks had warranty tags riveted to the side of the block.

T/A blocks were also sold to anyone that wanted to buy one.

Neither type had a stamped VIN.

The T/As & AARs I have seen so far with actual blocks replaced under warranty have regular 340 blocks.

They would just send out what they had to fix the issue, there was no guarantee that a T/A block would be sent.

1 the door sticker says 3-70 fender tag 401, block no vin 4-3-70
2 door 3-70 403, " "
3 door 3-70 407 " "

no vin on all motors all 3 same casting date on engine , trying to find out why no vin ? hard to believe all three warrantee with all dates that close. I understand schedule dates but everything jives for same time period. where there only certain dates they cast blocks? did they do them like they did for hemi"s in batches ? trying to verify if theses could possibly be orginial blocks, but need more info , can you help?

are the numbers on block below the drivers side head close

It would be impossible for any car built in March 1970 (assuming the door stickers you are looking at are originals) to have an original April 1970 cast engine from the factory.

in other words these could very well be the original blocks to the cars? do you have any documentation or is that speculation from your research? was there any type shortage on blocks? were they cast in batches ? or were the cars pulled of to side till ordered or blocks became available? just trying to nail it down . to many similarities to be confidence .just curious.

Did any of the cars in questions have numbers trans? Doubtful they would have stamped the trans and forgot the engine.

My car was a 407 SPD, not sure of the door sticker since it was stippered before I got it, the engine is a TA service block with I think a 4 26 70 date on it but for whatever reason I have no picture handy. Only is was put in when I built it in 13, in 72 it had a regular 340 short block installed under warranty, it had a 72 casting date on it. My trans is original and I am sure my original engine was stamped. So if you didn't know these facts then my car would support your theory, yet it has nothing to do with the assembly line.


I believe you have simply lucked up on 3 cars with service replacement blocks and yes, engines were cast in bulk and not every engine was cast every week.

I bought my AAR from the original owner back in 1982. It has a SPD of 403 on the fender tag. The engine in it is a non T/A, no VIN or assembly stampings warranty block. The casting date on the block is 7-2-1970.
I was told by the original owner that he bought the car new in Oct. 1970. He also told me that the car already had something like 700 miles on it when he took delivery. It appears that the not T/A warranty block was installed before it was originally sold new.
The auto trans does have the correct VIN on it.

mopargem that was also my first thought until found the other 2 cars with most of issues. that's why I asked if there was a strike or mechanical breakdown on the assembly line that might have stalled production. the thought of running out of blocks is a stretch in my mind,thats why im looking for documentation of any mishaps at the assembly plant , but all three vin's close and scheduled dates as Barry stated and all three blocks with no vin numbers and all 3 same casting date. does anybody have the warrantee records? as far as no way that the car built in march could have 4-3-70 block I would have initially agreed with you but im reminded of the battle between welborne and castaluchi over who has the last hemi car built.(don't kill me if I spelled the names wrong) that's why I never say never, and that's why im trying to find more cars built 3-70 and 4-70 to see if there are anymore similarly built. by the mopargem whats your fender tag and door sticker dates?

I believe all AAR/TAs were built from late Feb to maybe April 17th with the pilot cars being Feb 17th area, Barry can confirm, so most all of them were built in your 3-4 70 time frame. Lots of service replacement T/A engine and lots of people search them out for all the AAR/TAs missing their original engines.

My VIN is within 60 of his.

What about tranny numbers?

mopargem...
Another H4 bench seat AAR. My AAR is also a H4 bench seat car, but what is strange here is that your tag also has the bench seat code C65 and my tag does not. I had always thought that the fender tag on theses cars never got a bench seat tag code other than the H4.

my TA was built April 15 of 70

I've been working on a number of "ACTUAL PRODUCTION DATE" calendars based on broadcast sheet info - this will help answer some of these type questions. The constant "when was my A12" built sparked this idea , but its theory/method - I believe - is sound. It will be a long process but I've been working on the following:

Lynch Rd. '69-'71 (A12, Superbird, "last HEMI" & others)
Hamtramck '70-'71 (HEMI E-bodies, TRANS AMs & others)
St. Louis - '68-'71 (Chargers & others)

'70 HAMTRAMCK assembly LINE #1 (smaller line) - I've got most of March & April figured out (I think)

AAR on eBay

this AAR was on "SCHEDULE" "In Process & In Plant" on April 9, 1970

I know, pretty unamazing with a 410-SPD but that was the first b'cast I found on eBay.

so, any b'cast sheets? post them, PM, or email

I've not seen C65 on a '70 e-body fender tag either.

the Angelucci VS. Wellborn "last HEMI" controversy - second time I've seen mention of it this week - start a new thread

My friend has a V code Challenger R/T that has a build date of 7/30,I was telling him that he may have the last 70 Sixpack Challenger built. Do you have any built after that one Dan?

Barry has cars in his database later than mine, but does your friend's car have a broadcast sheet?

I don't believe they were still building 1970 cars 7/30/70 (& I have not seen any '70s "scheduled" after 7/30)
- that's a "SCHEDULED BUILD DATE", I know of one 7/30 car built at least 2 days before my 7/02 car.

What's the sequence number, upper left seven digits?

1-106533 is the last V-code Challenger R/T built that I know of & it was "SCHEDULED" 7/23.
