63 Impala birth date

[Deanlow]

Can anyone help please?
I'm trying to work out when my 63 Impala was actually built. I know it was built in the LA plant. It has a 250 hp 327 .that seems to date as sep/23/63 and differential dates as July/26/62 and code AW. So with the engine date I'm thinking it's not the Impala original engine.
Can anyone offer help please? Thank you

Post a pic of your body trim tag.

September 1963 would be the 1964 model year…….. it’s a nice looking ride

10A October, first week is the cars build date. That can be found on the cowl tag, upper left area.

You're very lucky that your Impala was built at the Van Nuys plant because, as well as the date code 10A in the top left corner, meaning first week October 1962, the Van Nuys cars from 61-early 64 also included a broadcast date when the car was built on the ACC line, in this case the 5 means your car was broadcast on October 5th and usually built by Fisher the same day, then sent to the Chevrolet plant (same location) for mating to a chassis and drive train and final assembled. Only Kansas City and Van Nuys Fisher plants stamped a broadcast date in 63.
