Yes. '46 was immediate post war production restart. The half ton pickup was shipped with two different designs that year. The first design trucks have CK prefix serial numbers. The second design trucks have DP prefix serial numbers.
This is also the beginning of the transition away from stamping the engine pad with the vehicle prefix/serial number in favor of the YAP coding scheme with a unique engine-transmission/application/mfg-plant serial. Transition is the key word here. The BG and BL prefix on '42 and '46 235 engines are in fact a carry over from the '42 Sedan Delivery and the 3/4 ton truck Series vehicle prefixes.
By the end of '46 a second design 1/2 pickup would carry a DP vehicle serial prefix and a DBx or DEx engine serial prefix.
So I think you have an original engine that jibes with a 1st design '46. Only the casting number on the crank can tell us if it is a 216 or a 235. But it is most likely a 216 because the 235 was typically found only in long wheel base applications: 134.5" (1 ton+), 160" (dually), and 160/195" (bus).
