For a 1980 engine, the practical thing would be to get rid of the car selling it as or for parts.
If it is a keeper, rebuild the engine.
As for the other problem: If you have solid proof, have whoever did it prosecuted. Do not escalate, unless you want to go for broke and pay the piper in big house time. Whoever did that is deranged or unconscious of what has done, and may know no limits.
Good luck. JV
