Otto,
The cab is a 1940 KC 1/2 ton built in December 1939 (per the ID tag).
The engine block and head indicate that they were manufactured in Flint during November 1953. The stamped serial number on the block is is 0022I 39 F54Y which (per information supplied to me by Gdads51) indicates an engine built for the 1954 model year, 235ci, originally with hydraulic lifters and for use with an automatic transmission. (I have not investigated the engine yet at all. It is all very nicely painted gray and the story I got with the truck was that it was a crate motor. Perhaps it was rebuilt? My thought is that I have no REAL idea of what the condition of the engine is.)
