383 engine decode

[Bogey]

Happy new year all. I'm trying to decode engine block from running 383 I just pulled. The casting is 2468130 8 followed by a DN below. Not sure what the DN references. Also the serial number is 0B276819 and not sure what the B means?

Any help is greatly appreciated. Am replacing it with 440 so trying to determine value and possibly someone looking for this to make their ride numbers matching

0=1970 , B=Hamtramck plant The rest is casting info.

Thanks all for the quick replies. Very much appreciated. Here's a pic of the pad by distributor. F383 followed by 69 and lastly HP

B = Hamtramck plant = E body as they that would be the only option for a 383 from he Hamtrack plant for 1970.
276819 = Looks to be from a string of Challengers.
