Honestly I'm not sure what more there is to learn about the limits of a stock block, it's kind of been beat to death on here before. But you know someone has to chime in and say they prefer this to that for the block to live and then someone else has to make snide comments just to stir the pot without adding a dam thing and then on and on it goes. I've said it before and it fit's, this place is like watching the classroom scenes at the beginning of kindergarten cop most of the time.
