Cryo treating blocks?

Any engine will last at 700 horsepower. The question is for how long. For most a long long time going to 2-3 races a year, a cruise here and there, ice cream every other Sunday. How many builds get ran one day on a dyno then off to be installed in a piece of garage art.
I agree and that's why I'm doing ad much research before I even start the build. Now some may ask why I'm going to such lengths to research how to keep a factory block alive instead just getting a race block? Because I like to learn the knowledge and because factory blocks are around every corner for cheap so if I can learn to make them last it helps for future builds in the long run. For me making it last at 600 hp would yes be maybe 2,3 or 4 races a year plus street cruising. I've talked to a handful of people running 340s and 360s in the 575 to 650 range that have 4 and 5 years of hundreds of runs a year that are still on the original build. Some have pulled out the engines for refresh but others say it still runs like brand new. That's my goal
