You always here how hot rod engines are balanced and blueprinted. I think I understand the concept of balancing an engine. You spin the crank on a specialized machine and machine as necessary to make sure there inst any "wobble". You then mate the connecting rods to the pistons and weigh them all to make sure they are exactly the same. In theory the resulting engine will turn as efficiently as possible.
So what is blueprinting? How is it done and what benefit does it provide? Can it be done in a home shop?
