S/B stroker block prep

Ok. This is going to be an on-going issue, with a multitude of uninteresting pics. It will be slow, since parts are still arriving and work will progress slowly.
The (late) repro block is the basis of this build, but much of the modifications can be expected with the newer R3's. This block has the 4-bolt main caps, extra material around the pan rails, more material in the lifter areas, thicker decks, and thicker cylinder walls. Mostly on the thrust surfaces. Chrysler expanded the water jacketing also.
