Quote: Look at the placement of that hole, it's not even in the center of the rod throw looking at this picture .
Very informative thread BG ...
I don't know for sure, but remember there are oil holes going from the rod journal surface to the main bearings. So, placement of the lightening hole may not be able to be "centered". Depends on lightening hole dia and location of the oil holes.
Good point Jim,I'am going to look at the oil hole passages tonight.
