Ross racing pistons (big block)

These were assembled in a short block but they were never ran, like new condition. I am leaving the rings on them as i do not know what brand they are. I did drop one by accident there is a pic of the damage, other than the one spot these are like new. All the wrist pins and clips are included. I have attached a link to summit for all the specs. I am located in Grand Rapids MI, would like $500 shipped. http://m.summitracing.com/parts/ros-99543
