515 - may 15? Or is the first one a 3

Looks like May 15 to me. (515)

We’ll never know the build date but the Scheduled Production Date looks like 515.

Oh no it’s suppose to have original engine I got the rt off the original owner but the date casting on engine I think is 6 20 67

I tend to think that if a 50+ year old car still has its original engine, it just wasn't getting driven hard enough by its original owner. Lots of musclecars lost their motors early on. Just be glad that it got a replacement and carried on. LOL.

As Doug (69Coronetrt) mentioned the 515 is the Scheduled Production Date... It may or may not be the actual production date.... My Challenger has it's original engine that was assembled the day after the cars SPD... But the Assembly Date stamped on the axle is three days after that... The K member day was stamped the same day....

Actual Assembly of the car could be months different from the Scheduled date..

At the end of the day does it really matter?

HP stamp?

Casting date only accounts for a bit.

Agree... Is the 6 20 67 a casting date or is it stamped on the pad?
Stamped = Engine Assembly Date...

A cast date of 6 20 67 would most likely be assembled a couple months later making it a 68 Model Year Engine...

HP stamp?

Yes c 440 hp

Also got the car off original owner but the casting date is I think it’s a 6 20 67

 

[eldubb440]

I'm betting it's the original

is that date cast into the block or stamped on the pad?

Let's not jump to conclusions just yet.....

1) What is the engine assembly date (EAD) stamped on the pad in front?
2) Clean up the fender tag so we have a clear viewing of the SPD. Is the date in fact 515? Take it it off and flip it over if necessary.
3) Check all the other date coded components you may have access to. Check dates on things like mirrors, glass, radiator, transmission assembly date stamping, voltage regulator, wiper, steering box, hood latch, etc to see if there is pattern of dates. There's always the possibility that the car was built 'late' or well after the SPD. Let's see if dates on other components align with the EAD.
4) Pictures. You're asking us to help and see what you see with no pictures and minimal descriptions. We need to see what you are seeing to give you useful answers to questions.

This is this is on the pad and the transmission is number matching?

May 2nd 67 Engine Assembly Date.... In my opinion you are good...

 

[RemCharger]

May 5th 67 Engine Assembly Date.... In my opinion you are good...

I'm seeing a 5 and a 2.
And the cast date is a 6 and 20?
Wonder if the noted cast date is incorrect

5 & 2 is correct.... When I changed 5 to May my brain put a 5 where the 2 belongs... I corrected my post....

Yeah, something was probably read wrong on the cast date, they often have casting slag that makes it difficult to decipher....

 

[coronetmaniac]

is that date cast into the block or stamped on the pad?

Cast in block
