Have a 1946 2 ton truck that I am currently doing engine work on. I want to make sure the engine is a 1946 235. If not then what year and what engine is it.

Stamped on the block just back of the distributor is: DEA558832

On the top of the head is stamped: 839491 A207
CONV 13 or Maybe CONY 13.

Thank you. Jeffrey
