3836850 - head casting code - 261 head - many years
If C 8 2 is the head date casting code (PHOTO 7 on my page), it is from 1962
C = March
8 = 8th day
2 = 1962
"side of the block is B59 / 848 / 850" - no meaning for this code (if this in location of PHOTO #4 on my page)
If C114 is the block date casting code (PHOTO 2 on my page):
C = March
11 = 11th day
4 = 1964
That would be a replacement block (1963 was last year a 261 was regular equipment in one model of trucks, supposedly).
No block casting code: PHOTO 1
between and below the distributor hole (left-top) and road-draft-tube hole (right-top)
261 is a good bet
By the way:
Con 9 or Con X was simply the Conveyor number in the factory - it is not useful in ID-ing the head or block or the year/date.
