Help me out here, even with all the time I spend on the boards, I do not know whether or not the LS1 uses aluminum in any of it's bearings. Someone asked me this and I am stumped.

Most bearings are tri-metal and this consists of Babbit, copper, and steel for backing.They usually come thru with a thin lead coating for dirt embedability and to help with dry starts. But i dont know specifically what GM uses on LS1 motor, sorry Patman! <img border="0" title="" alt="[Roll Eyes]" src="images/icons/rolleyes.gif" />
