Honestly,how strong are these 360 magnum blocks?

I've heard conflicting evidence. Some say that they are the thinnest casting of all 360s. Others say that's bull and that their high nickel content makes them very durable. I've run both the 318 and 360 magnums with N20. I put down over 500 rear wheel HP. I daily drive and race mine all the time spraying off the line. I've never had any problems.
