However, there are shims installed at the factory under the main bearing caps
in a lot of 235s and 261s. Ever notice those really, really thin sheets of
metal under the mains? Typically under the rear bearing cap? It's critical to
keep track of these guys during disassembly and put them back in the exact same
spot. If you lost or forgot where they go, wouldn't line boring the block take
care of things? If you talk to some Inliners, they always line bore their
block anyway. I suggest you talk to a machinist that is more familiar with
your situation. Good luck!

Either this guy is confused, or you have an older motor. The older babbitt
rod motors used shims on the rod bearing caps, but later 235s use insert
bearings - no shims required.
Most "production" machine shops don't want to work on older engines, as it
takes more time away from their more profitable operations. It's usually
better to contract with them for just the major machining operations and do
the assembly yourself. Or else find a shop that specializes in older stuff -
but be prepared to pay more.
