A line bore job is a real PITA, as most shops don't actually "bore" anymore- - - -they hone the main bores. On a stovebolt that would require a very special, very expensive hone mandrel capable of having four diameters set at once. The shop where I ran the connecting rod department actually had a line bore machine, so we could set up a block with four cutters and do the whole job in one pass. It might be good to mention that the old boy who ran that machine was in his late 60's- - - - -before the turn of the 21st. Century rolled around! I doubt if there are very many machinists still working for a living who remember how to set up a machine like that!
