GM Timing Chain Damper
It looks like a good thing to do.
According to the post at the link below the 97 and 98 corvette blocks had holes tapped for this. I wonder if the 98 Fbody block is tapped.

Guess if your crank pulley and timing cover is off or if you are doing a cam/chain swap, it's a good time to think about it.
Cost is around $85-100 for the damper.
