I have read through past threads but not gotten too much help from it thus far. I am looking to purchase an flex (ball) hone tool for 4G63 blocks. Up until now all of the motor rebuilds I have had to do I was able to borrow a flex hone tool from friends from his shop. However he has since moved and thats not longer an option. I have talked to a few local places but none have what im looking for or read I needed.
From my readings I see best results with 240-320 grit, is this correct? My local place only has 120 grit but I can order online a 240, no place thus far has anthing higher in the right size. Also I can not find metric... ive located a few 3.5inch units which are "good for" 75-90mm bores (obviously our 85mm will fit in there fine) Im willing to just order one online but wanted to ask here before I do. Thanks
