Are there any problems getting false knock if you are running solid motor mounts?

 

Are you talking poly mounts or something else? If that's what your talking about I dunno how it would make a difference anyway. Without knowing from personal experience I don't want to speculate too much, but I'm gonna say no it would not cause any problems. All the solid mounts do is stiffen up the sloppy or torn factory ones. If anything they might help prevent it by not letting the motor tq so much under acceleration and having something like a header hitting the frame or anything. Usually when people do a header install they change out the mounts also to prevent this, not to mention just to revive the old and tired stockers.
