You learn something new everyday. How long will an LA small block hold up at 550 horsepower

dyno mule, bored .100 over.
There's a difference between a mule and weekly race engine.
My main point wasn't the engine in the article but the treatment, don't know much about it 1st time hearing about it, looks like it cost $600 for the block and $1000 for the whole engine but if does gain 30-40% strength probably worth it for a 550 plus hp motor.
