Though Rick is right and all the different literature will back this up, oddly enough there are two things I have NEVER found on an LS6, that radio ground or the valve cover to firewall grounds. 396 cars, yes. LS6's? Never. Don't know why just stating what I have found. Engine size should have NOTHING to do with either one of those but evidently it does.
