trex and nitrous
Terminator (on this board) uses a similar cam (in that it's really large, the LSA is higher) on his stock motor with a 200 shot of nitrous. He has a bunch of passes on it and to the best of my knowledge no damage.
On the other hand, a lot of people here bust ring lands on mild shots with no cam. There was also another company (forgot who it was) that tested a kit on a stock GTO and blew the headgasket pushing 200 or 250HP out of the hole on the first run. That should be somewhere around a well tuned T-rex with a 100-150 shot but they have the better motor.
