    Ive always thought that the amount of wear allowed before you condemn a block, or bore it over, should be some what dependant on the HP.

    Im personally, more worried about .005 over on a 3hp, say than a 40hp. (relative right)

    How much wear do you guys allow, before you decide it needs to get popped up a level? Limit this to the 50s 60s OMCS for now.
