That sounds just like my sister's car.
If it is a piston/rod bearing problem, you could eliminate it by pulling one spark plug at a time and see if the noise changes.

Define rebuild? everyone has a different idea what a rebuild entails? did you keep the BS?
It sounds like valvetrain, lifter issue.

The rod knock I've encountered always got worse when the gas was applied, or when it was revving down.
Take off the valve cover and see if you might have a rocker that fell off or maybe a faulty lifter.
