magnum bore wear???

HuH, you learn alot of new stuff in a day. Interesting about the lead. Would make sense as how when lead stopped being used in fuel, POS cars started lasting longer. Look at all the 80's garbage that is still on the road today. You know they are the biggest POS cars on the road yet somehow they are still going. Would make sense that lead was causing additional wear. Look at what oil you run affects your engine wear
