Are ALL GM Engines ok for all GM Model Cars?

The 3.8 is a nice engine they can be a power house built right just look at how many grand national can carry the front end drag racing.As far as a engine swap if the engine your using better have more hp and torque then whats in there.Gm is good at using one engine in a lot of cars look at the old 2.8/3.1 or the 3.8 used fwd and rwd in pretty much everything they offer at one point.
