So what do you guys prefer to use for precision measuring of engine specifications, bores, cranks, piston diameters, etc? Right now all I have is a cheaper (hobbyist) set of 6" digital calipers commonly found on the popular auction sites. Works good for general shop use but in my K241 work I came to find out quickly this is not adequate. I did recently order a set of the telescoping bore gauges. They were only 15 bucks so what the heck. Any & all opinions & ideas welcome.
