I have heard good and bad in regards to the Northstar engines. Supposedly, they are very durable internally, but suffer from seal/gasket failures and electrical gremlins as they get older.

The 4.5 and 4.9 Cadillac V8s from the late 80s- early 90s were very, very dependable and a lot of them are still on the road.
