you need 2 mics for engine rebuild 2 to 3 inch (for crank )and 3 to 4 inch or metric equivalent i use one like this,as once set to nominal bore size you can accurately and easily measure bore wear ,by gradually walking it up you can find area of greatest wear as well as ovality,it gives a much better and quicker picture of the bore, the only problem is your not likely to use it often
