340 block vin question

i have a 70 340 ( cast 5-26-69) i was looking at the block vin today and just curious as to its origin. pan rail vin is 0B124378 so its hamtramck but i have never really researched what it came from. anybody give me some insight? guy i bought it from had it in a 70 duster but he was not sure if it was the original motor or not. just curious

is from a 1970 Barracuda model, a Cuda since its a 340 in this case.

So the only possible matching VINs for the car it originally came from would be BS23H0B124378 or BS27H0B124378

awesome thanks
