  1. If you are not going to bore the engine, just order O.E.M rings and reuse the pistons. Do a quick hone job and slap the new rings on and your good to go.

    If you are just looking for a way to measure the factory bore to make sure it hasn’t been bored. You will need to use a Caliper. Less than $20
