Part of my reasoning comes from some engines that came to me with blowby issues,and larger than what I like ring end gaps.
One was a very low milage MP shortblock.But I suppose part of the problem could have been related to wall fnish,as Vic was saying.
After a rehone and fresh rings,with tighter gaps,no more blowby issues.
But I ended up polishing the crank also,as the finish on it was horrible,so maybe the finish hone was crap from Mopar too.
