I guess I just take more time in doing motors perfect,this is not something you want to learn,cause if wrong then u have to take the whole thing apart again..a hone.boreing machine is the ONLY way to get the walls the way they need to be...it crazy I always see some of these people who posted here always say don't cheap out on thing yet they r telling him its ok to do this..I'm sorry I guess its just my 2cents..altho I would love to see a self honed block have perfect. Mirror finish with perfect crossing
