Take a look under the valve cover, look for a broken valve spring near the end. Check for any valve train problems, loose studs, pushrod wear etc.
If none, try pulling spark plug wires at idle, one at a time, pull from the cap and be careful not to get shocked.
See if there is any change.
DONT pull the plug wires if you have an HEI distributer. They can develop enough spark energy to arc down to the module and blow it.
Listen to your brother in law!
Good luck, David
