Help identifying this 429
« on: September 24, 2015, 09:19:45 PM »
I picked up this 429 recently and am trying to figure out what year it is. Not as much info out there as the 390's and 472's. I did read that it is likely a 65-67 based on the water outlets, I just don't know which year as it's been out of the original car for years. I also read that each year have different manifolds. Anybody know anything about that? Also I would love to know which years this motor fits in. Any help would be much appreciated.

The 2nd pictures had the VIN# which identifies this as a
S - from a 75 Series Limo; 6 - 1966,   159137 as the production sequence number starting with 100001, or the 59,137th for that model year.

Thanks! So now I am wondering what is different about the limo transmissions vs the regular model ones? As my Cadillac interchange book says they are different but does not say why. My assumption would be length. What is weird is that the guy I got the motor from had it in a 73 Sedan Deville and said it all fit perfectly. I hardly believe that but I'm thinking maybe it could be true because the limo length. Its my understanding that cars with a 472 are not a direct swap and vise versa. Any thoughts????
