If you had such a mismatch, you'd probably have NO
oil pressure and some knocking rods. You may have .001 or .002 polished undersize that could create a drop in pressure, but not a .010. The cruise rpm doesn't seem too bad but I would not want only 10 psi at idle. Loose clearances are aided by a high volume pump, but I'd probably yank the pan and re-do it.
