Engine Swap?

I've got a 91 6000 w/a 3.1 L V6, and I'm wondering what cars this engine would swap into. Specifically Buicks. Our 6000's body is crapped out, and the interior continually smells like mildew, no matter what we do, so it's time to retire the old girl.
Redid the engine about 6000 miles ago, and do not want it to go to the crusher with the car.
