The engine number is right behind the distributor, stamped onto a flat machined surface. The date of manufacture is on the driver's side of the block, cast into it.
SOR has a page devoted to engine serial numbers as they relate to the date.
Specter Off-Road, Inc.-Landcruiser Parts & Accessories -Engine Serial Numbers

The block pictured was cast on December 18, 1976(6=year...1976, 12=December, 18=day of the month)

So when was this block cast?

All I see is the Shroud of Turin

Maybe it applies only to 2Fs? Either that or yours was cast on November 14, 1971
That would mean the "code" changed....but the short answer is...I don't know.

Well, it IS the block in my 71 , and I also came to the conclusion it was a 11/14/71 but the tag on the body says it's a 2/71

It's all unmolested OEM also...

Cooler, trying to decode the 10 digit Toyota part number as a date is not gonna work.

Date code is at the opposite end of the block from the part number. Look for the smaller typeface 5 digit number toward the front of the block.

Here is a place to start. I seem to recall seeing someplace more serial numbers for later years.

SOR Engine Numbers.

OK, Jim that block number is 10210. (Feb,71 10th day?)

I did look up the engine number (F342050) on SOR long ago. SOR says it's a Feb or March 71. I had just never heard of the block date casting number. Still learning guys...
