I have a friend that is telling me about a cryogenic process for metal that is
supposed to align the molecular structure in the metal through extreme cold.
They claim to be able to take a cast SB Chevy crank and after the process it's
supposed to be BETTER than a steel SB Chevy crank. anyone ever hear of this
being done?
