this tag came with the Rebuilt (312) Y BLOCK I bought on E-Bay out of Troy N.Y. I sure could use some help with what it says. I will attempt to post a scan so those of you, better than I, can try to clean it up some more.It appears to be a real good build but doubt it is a 312 unless bored to a 312
