Larry:
I suspect it is more of an issue with outboard racers and us bike guys,
since we have aluminum blocks. Iron blocks change dimension a lot less with
200 deg added heat (due to the lower coefficient of thermal expansion) so
the return-on-investment (in dimensional accuracy) would be much less.
Perhaps that explains the minimal response?

Subject: block boring
There wasn't much response on warming the block to operating temp before
boring and honing It must not be done much. We race outboard motors and
years ago
a motor builder was doing this is the reason I asked. Sounds like it would
work for the high end racers.
