One of the bolt holes in my block (440) is stripped (one of the long ones in the middle). A couple of questions, can this be helicoiled, what size/pitch helical do I need. And most important, does the bolt hole go all the way through to the crank case, or is there a bottom to the hole? I don't want to push any metal shavings into the pan. I have masked off the top of the block in prep for drilling.
