What makes a stroker piston?
Some venders advertize stroker pistons for the small block Olds,so is it that they are a larger than standard over bore with the olds pin size?

Just so we're all clear, the term "stroker piston" is a misnomer. Stroking a motor involves changing the stroke on the crankshaft, which has nothing to do with the piston directly. Changing the stroke while keeping the deck height of the block fixed requires changing either the rod length or the piston compression height (the dimension from the piston pin to the top of the piston) to keep the piston within the deck height of the block. Depending on the rod length used, you may or may not require different pistons to stroke a motor. Note that the longer stroke also pulls the piston further down in the cylinder at the bottom of the stroke, so the pistons may also require tailoring of the bottom of the skirt to clear the crank balance weights.
