N/A 3800's routinely would last over 250,000 miles. but by then the rest of the car was usually shot. And the transaxle they were bolted to had been rebuilt at least once.
The supercharged versions were good engines also, just not as long lived.

This. The 3800 V6 is one of GMs best engines ever.
The 4.3s are good engines, also. Routinely go well over 200K with no issues.
