i spun the rear main baring in my inline six. so i sent it out to get line bored going through napa. the machine shop calls me and says that each journal on the block is a different size so they will have to bore each one individully also tripleing the orignal price the quoted me. it doesnt make sence to me and to everyone else ive asked. so, have any of you line bored your orignal engine and had this problem or even heard of it?
