What do all the stamps on my 360 mean?

its a 318. if it was a 360 there would be a 360 in that number POST A PIC LOL, the VIN number will be stamped above the side/ rear oil pan rail on the passenger side. post a pic of it. you may have to do some scraping to find it
the-318 is cubic inch and i believe the 23 following it is the date code but im not sure.

That 23 could also be a casting revision number. Meaning everytime there was a upgrade to the casting the factory would go to the next highest number. I know this was supposed to be a 1977 engine, but still, i have never seen a number that high?

On a more positive note at least you know what to look for when checking out another engine:D.

Man you got so many threads going now i'm having a hard time keeping up?????????
