Sorry but I kinda chuckled when I read the title of your post. In the late 70's my Friends and I flew down to Daytona Beach for a little vacation. My one Friend was reading a National Dragster magazine and said hey Crane Cams is nearby so he called and arranged to take a tour. We really enjoyed the tour and towards the end of it sat a little old lady hand spinning pushrods in a jig with a dial indicator and smacking them with a hammer to straighten them out. LOL at quality control at its finest.
