Hi all,

Here is some Caddy casting number info I came across a while ago, while I was trying to decipher my engine numbers. It's by far not a complete list, so if you can add to it feel free to do so, or send me the info and I will include it. This may be better placed elsewhere on the board, but I wanted to put it here so it would be seen by anyone who might find it useful.

The info came from a site called "Swap Meet", but I've never been bright enough to find it after the first time I stumbled upon it. It is accurate for my engine numbers, but further than that I do not know so use it as you see fit. I have it as a word document if needed.

Thanks Ken. Just bought a Caddy V-8 & not sure if it's a 331 or later motor. This helps.
