Re: 1947 Packard Clipper Info

If your patent plate is still present and screwed to the cowl all the important vehicle identification numbers will be on that plate with the exception of the motor number. Packard only placed official numbers in a single location so if your patent plate is missing, there is no other place to find the pertinent vehicle number for the car. Also, if the engine has been swapped the original motor number will be lost. That is important because in some places registration was done by motor number instead of the official vehicle number.
A number similar to the official vehicle number may be found on a small tag on the engine side of the firewall as placed by the body builder. That number can differ from the official number by several digits depending on where the body was placed on the assembly line. A large embossed number is also on the firewall but it was never used outside the factory and surviving documentation to link that number to a specific car is no longer available.
On a 21st series 46-7 the motor number should be stamped on the engine block slightly below the head/block parting line and in the area around the distributor. Sometimes the motor number stampings were faint and they could be covered in dirt and grease. You may need to use a wire brush and do a good cleaning to find and read them.
On the last page of this service counselor is an article where Packard compiled and listed the range of all pertinent numbers for various years.
The chart at the bottom of this post is information from the Clipper parts manual showing the various Cipper body identification numbers and which chassis each model was build on. Those are the numbers that should be found on the patent plate.
The other chart posted here is not official but was compiled from various sources and put together -- mostly by BigKev -- as a reference to the size and details of the various engines by motor number. If your motor number does not start with the letter "F" as listed it is not the original motor.
