No. 5 Cylinder has busted piston, getting ready to pull out, if block's OK, might rebuild but has just under 200K on it, would be good time to replace w/low time engine.

Welcome to CF. If you replace it with a newer engine just remember to use your '99 sensors, or replace them with new 'ones for a '99 so they still work with your Powertrain Control Module. The connectors might have changed, or you might have issues when using different sensors, and it could be hard to diagnose, if it would even run.
