Works for all the engines I've built ( for my self and when I had a shop) .
If a absolutely round bore and round ring could be made, break-in would not
be needed. Since this is not economically feasible, we must leave the bores
slightly rough, assemble them slightly tight then let them wear in.
It promote ring break-in, Total Seal rings says to lightly oil the piston
skirts and leave the rings dry. This works as I've done it on my Formula Ford
(
1.6 Kent) engine with no ill effects. The other key is to warm the engine
just before use then use short bursts of full throttle then let the engine
coast,
the coasting draws oil past the rings washing out any metal shavings from the
break-in process.
In short, high RPMs are not needed early on, rather the engine needs to be
worked ( loaded ) in order to breakin.
