Looks like an original casting number for the first 351Ws. Casting numbers here:
Kelly hotrod - Ford Engines Page 2
0b25 is probably the date code. "0" for 1970, "b" for February, "25" for the 25th of the month. They let the blocks sit for a while after casting, so your block probably ended up in a mid to late production 1970, for any model using the 351W.

Looks like the 250/300 ratings were the advertised HP for '70.
What are you doing with your motor?
