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.

I’m having trouble figuring out which motor I have. Block casting number is 1461476 Stamped into the bell housing (driver side) Is 4V5269 Stamped into the front left deck is 556206628 And ideas?? Pete
On all the lists I have saved. Has it as an Olds. Maybe bad info. One PDF from a google search has this. Cadillac 331 54-55 #1461476 w/o integral bell housing
Serial numbers and engine numbers were the same again. They appeared on a boss on the front right hand face of the engine block; on the lubrication plate on the left front door pillar (1953-1957) and on the right frame side member behind the motor support. The first pair of symbols were "55" to designate the model year. The next two symbols indicated series as follows: "62" = Series 62 including Eldorado Specials; "60" = Series 60 Fleetwood; "70" = Series 70 Eldorado Brougham; and "75" = Series 75 Fleetwood The immediately following numbers, beginning at 00000 for each series, indicated the production sequence in consecutive order. Ending numbers were the same for all series since the engines were installed in mixed production fashion. 1955 YOM, 62 series engine, http://forums.cadillaclasalleclub.org/index.php?topic=119266.0
Hi guys. I was a member of the H.A.M.B. for a long time, but that was years ago. "Life" happened, a little boy was born, the career changed... Yadda yadda yadda. So anyhooo, stumbled upon this thread while researching something I found on a '58 Caddy thats been eating away at me for a few weeks now. It's nothing outrageous or anything, just... odd. I pretty much determined it was a 365 based on the 1465061 casting number on the intake. It's just a standard 4V intake as far as I can tell, but EVERY SINGLE OTHER INTAKE I've found anywhere online with this casting number is followed by a "-1", whereas the one I put eyes on a few weeks back was followed by a "-2". I've been unable to find another with this casting number followed by a -2. Any idea what the dash-digit means, or why this one isn't like all the other kids? Thanks in advance, and I'm hoping to rejoin the little family of guys that build go-fast if you'll have me!
