Cadillac Engine Serial Numbers Directory
« on: May 19, 2016, 01:55:51 PM »
Hi!  I have been trying to find a Master Directory listing all of the Engine Serial Numbers from year to year for Cadillac V8 engines - particularly the 1930's thru the late 1940's.

If anyone could please provide information about a directory such as this - even online - that would be extremely helpful to me (and many other people -I'm sure- searching for information).

I have a 41 Cadillac that has a "Correct" looking 346 V8 engine.  I'm certain that its NOT the original engine as it has an Engine Serial Number Stamped on the front corner of the PASSENGER's Side of the block  facing upward.

The Engine Serial Number reads as follows -  Engine serial numbers have a "Star" shaped symbol at the beginning and at the end of the numbers sequence.

Star Shaped Symbol in far left position ...then the numbers -  8 4 3 5 8 2 1 ... then another Star Shaped Symbol on the far right position.

Can anyone please help me identify what YEAR of engine this is?  Any information would be appreciated. I need to do some engine work and I'm not sure what parts to buy.

Thank you in advance for your help!

If you can also please email any information to me directly at ..... .... that would be appreciated. Not too sure at the moment if I'll be able to find my way back in here to check for responses. (Not too computer savvy).  Thanks!

Check the front part of the CLC Directory.  There's a table showing the serial/engine number ranges for various years and engine types.

If you are a CLC member you will find it in the directory mailed to all members.  Starting on page 62. 

The number you provided is for a 1947 series 62 engine.

will this help you?
When a Doctor "saves a Life" it does not necessarily mean that that life will ever be the same as it was, but he still saved it. My 46 may not be as it was but it is still alive.
