Little Help Deciphering Engine Number

[jd52cranbrook]

 

 

Hello,

I just purchased a engine from a friend that came out of a early 60's Power Wagon.

Also, this engine was a replacement that his dad bought from Sears way back.
It has a Spitfire Head, although I know it may not have been original.  It is the long block.

Numbers as best I can read are;

This is where my P23 engine number is located, driver's side, front close to the head.
N258979CAL

Another number on the block, close to where the starter is;
1138129-5, I think this is the casting number

Any help as to what size motor this is?  Everywhere I looked on the internet do not show a number starting with N,, but this letter I am sure of.
Thanks in advance

I was able to use the casting number to find out it is a 251.  The rest is a mystery still

If that "N258979CAL" is stamped into the block, and not a casting number (raised) it is either a number assigned to the engine by a rebuilder, or. judging by the "CAL", the State of California,

Yes, I believe the raised numbers toward the rear by the starter is the casting number, the 1138129-5.  It's the one I used to determine it is a 251.

I think the D24 means 1946-48 Dodge, 230 ci.

Heres a couple links I use that may help.

a spit fire head is for a 25 inch long block.  So its more likely it is a 251.

FYI, I was referring to the post by Dixiepaul rather than the earlier one by jd52.
