1940 Chev C15, Cab 11 restoration in Holland

[jaap de wit]

thanks for youré reaction about the engine david.
the mark on the engine is H-3-2 (aug 3 1942) and the motor no: MR 3849823
and the GM 839253 number cast on the side of the engine block.
so now is my quiestion david by what nunber can I see that the engine is for a C8 or C8A ? I know the engine must have been placed in the truck on a later time as a replacement but thats it for me ?
I hope to learne more about this.
cheers jaap
