Scroll down on this page to Tech Tips - 2005 and read what Iskenderian has to say about it.
http://www.iskycams.com/techtips.php

Then, there's the issue of the 6" rod putting the wrist pin up into the same area as the oil ring. I don't care for more complexity to support the rings, so I would use a 5.700" rod in a 383/388 build. Keep it simple.

As Ron Iskenderian says in the tutorial, change rod length ONLY when you have exhausted every other avenue in your quest for power.
