I’m updating this to help with accuracy of the excel doc that’s tracking this. My FJ40 is from Colombia. The numbers on the engine plate are 2F 081966. The block casting date is 60323. Using post #3, as reference, it appears my engine block was cast for the South American market on 3/23/76.

The block numbers are as follow: (image below)

11411-61011 (Image A)

The head has following numbers: 61010 then 031082 (Image D)

SOR said my head 61010 was from an 8/80- 8/87 2F? Can someone verify?

What do these numbers mean? I just cleaned mine up and saw these numbers.
I’m not sure but hope the knowledgeable MUD community can educate us. Anything I share is conjecture. However, after reading a bit more in this thread, I updated my previous post referencing the images now as A,B,C,D).

A - Part number for engine block
B - Casting date of engine block
C - Unknown?
D - Head number part number first stamp (still not clear on what second stamp number sequence are).

If I'm reading the date codes correctly.

1972 with a 2F motor - serial # question

Forum is great, I plan on absorbing all info I can possibly handle so I can bore non-FJ owners at every opportunity. This is my first post so hopefully I don't make a grave rookie error . If I did, please let me know what it was so I can toe the line.

Here goes: 1972 FJ40-137491, frame and plate at drivers side door match. Motor is immaculate, block has glossy black paint, eat off valve cover, etc. No smoke, starts every time w/o any choke. It is a 2F which I know makes it right off the bat not the original motor. The serial says 2F-877067 and from everything I am reading in these threads, no one's serial even approaches this high of a number.

What's the deal? Counterfeit Chinese motor? Candid camera gag? If it helps, drivers side number on block is 61014 which I believe means the motor was produced October 14th, 1976.

Appreciate the help, especially to a South Floridian :flamingo:
I bought a 2F from cruiser corps and the serial number is 879202. I've been trying to figure out what year with no luck.
 
From the spreadsheet on page 28, looks like 1986 ish.
