86GT 93LX

so its a 1980 255ci 4.2l v8 i knew it had writing on the back that said 5-12-89 so and with the fresher looking ford blue back there behind the flexplate/flywheel i have always assumed it was a rebuild from 89, i was peeking at it today and i also found more stuff written near by. on one of the freeze pluggs it has a capitol "B" and near it it says "70-M"
then not far from that it says "70-E4931-1" and "255" directly under that as well.
so im wondering what any of this means if anything at all, like i wanna know if its been bored over. wondering what the 70 means since it appears 2 times
