I have a V/S boring bar that came out of a Ford store. Was told that it was a special tool for boring the old inline 4 and 6 engines. it looks to be in great shape and has the tooling with it. even the original shipping crate with the leather packing slip. I'm thinking about trying it out since it does work. does anyone know anything about these. not much on line that I can find. Thanks for any help. If need picture I'll add them.
