Pretty much, except for control electronics, the '95 is OBD I the '97 is OBD II. So there is some subtle differences, but for the most part they are the same...

yes and no.... the 95 could be a ball and pivot rocker arm or roller rocker arm motor (change-over year, GM used both in this application), and the 97 is definitely a roller rocker arm engine. They are not compatible. 95 was the year GM started going to OBD-II, so if the emissions sticker on the donor car says OBD-II, and it has roller rockers, they should be virtually identical.
