Could be a rod bearing, maybe you can get us a video of this knocking? Moving the camera all around the motor so we can try to tell where it is coming from.

You checked the oil level or the oil pressure? I would advise against running it until you determine the problem---no point in making matters worse.

I would pull the valve covers and check the rockers.

I broke a valvespring and it was knocking as hell, thought it was a rod bearing. So it could be something in the valvetrain.
