I am aware of that view and even read a long article on it. However, it
only stands as 'good' advice for bedding in the rings and bores. I've read
nothing that suggests it's a good practice for main or con-rod big end
bearings.
My previous engine was successfully revved to 7,500rpm on an almost weekly
basis despite having a very steady run-in period. That engine was once
accidentally revved to 8,250 and survived.
The first 100 miles (actually 96) that the engine has been driven was done
in accordance with the engine builders advice. He has built a high number of
race winning engines as well as fast road engines.
Still, your view is as valid as anyone elses.

Hello Daniel1312,
others who have done engine rebuilds will weigh in (never done
one myself) but all the information that i pick up from
EVERYWHERE is to break it in by driving it like you stole it!
drive HARD, rev all the way up, shift do it again.. apparenlty,
baby-ing during break in can and often does cause ridges to
build up on the cylinder walls near the top of the throw.. if
you haven't been red-lining it you may never be able to!
