And Ron's idea of opening up the rods just a bit is a good idea - especially for high-performance usage where you want a lot of oil to flow. As we always said "loose is fast!".

Also, the way that you balance these early rods is NOT the same as modern engines - where you have a 'balancing pad' to remove material from. Many shops just grind the bottom of the rod - which weakens it. They need a special fixture that mounts the rod-cap in a lathe - where material is removed in the same manner that Ford did when they balanced sets of rods.
Since resizing requires a slight angle cut on the parting line faces, how is this done with the studs in the way?
