I got a quote to treat my full long block for $450. Makes the metal elements stronger and reduces friction from what I've been told. This is a major "while it's out and torn down" moment for me. The place is called 300below and is close enough to me to drop my parts off. They take the parts to -300 degrees and then heat them to +300 degrees. I got a recommendation from a fellow Z member just curious if any of you nuts have done it.
