You could drive a quite small bus through 60 thou. On my 3-bearing (shell, pressure fed) engine side clearance is about 5 thou.
I'd venture that unless the side clearance is very tight it's anyway bigger than the flow path between bearing and journal.
Chris Gould successfully brazed 'washers' onto the sides of the A7 rods he used in the 10,000 mile record car (n.b. not the 'special' set which were used for the attempt itself). This was to compensate for the larger BE offset on a Reliant shaft. A bit outside the scope of A7 running repairs though!!
