Hi,
I vaguely remember thrashing through this once before.
The key might be having the right machine shop. I bored out a set that
might have been 83mm or 86mm, but it is 87mm now and it spent 8 years in my
race car, with only one ring change.
They sized each liner to it's matching piston, and as a engine builder for
the stock car crowd they knew what I doing with engine. They are also very
familiar with wet sleeve engines and have done some custom work for John
Deere.
I have another set of liners on the shelf that will get bored out to 87mm, if
I should ever need them.
Sometimes living in Iowa can be a very good thing...
