Beenthere,
 
 Are you saying that badly off centered southern pine will not react or twist or cup ???

I've sawn a lot of wood, and this type of off centering has never gave much usefull lumber, but then I don't know much about Southern Pine, school me.

I expect the southern pine with that offset pith will behave badly (warp, twist, and/or cup).
More so than a 'western' pine with similar offset.  ;)

I'am no expert but I would slab it four sides and forget about it for a few months then true it up and cut to dimentions,there will be loss whatever you do. Frank C.

 Cut it up how ever you want , it will be a learnin' experience for you  ;) :P   Then you may do like me and saw those up to put on the ground to put logs on while they wait to be sawn.  :)

Wood will be wood and will do as it pleases,we can have our thumb on the scale somewhat but if its going to twist its going to twist.Cut it, stick it, with weight on top and move on. Frank C.

This is an absolutely perfect example of a situation that Dodgy Loner and I were discussing last week.  This is not an unusual example that you will find when sawing SYP.  The pith may even be offset on the other side of the log on the other end.  You can not make perfect lumber from an imperfect log, but you can not discard it either.  I have sawed many thousands of board feet of framing lumber from such logs.
 
We often talk about "centering the pith".  That works with good logs with almost centered piths.  It doesn't always work in the real world when sawing off center piths.

In this instance, you have to center the log, not the pith.  Take the boards off with the pith either close to the top or bottom.  NOT close to either side.  Watch for stress and rotate 180 degrees as boards are removed.

There is much that I need to do, more that I want to do, and less that I can do.

Never allow your "need" to make money to exceed your "desire" to provide quality service.
