Yes, the engine serial number indicates 1950 216. That number could have been punched into a later block.
The head indicates 1953 truck 235 (18 head bolts and 2 valve cover bolts). It could be mounted on any 53-55st block (which would use the high/exterior mounted water pump).
The block casting code would allow further identification (and/or further confusion).
In an earlier post about this engine, I think someone posted that it could be a Canadian engine, which offers further confusion?
It would helpful to have the:
(1) head date casting code, and the
(2) block date casting code, and the
(3) block casting code.
