**600hp sbm block limit? Or is it bs!!**

Supershafts said

I never used a stud girdle and put in 400hp on 2 stgs, i have broke cranks, pushed out gaskets, but not the block using n2o, but i leave off idle on the system and that seems to play mayhem on the bearings which will make them need changing more often.

So would you guess about 800HP? You have some serious shock going on in the bottom end also!

Most of the failures here so far seem to be clearly from the other parts of the engine failing and then they take out the block.

Getting to the bottom of this 600HP myth, I appreciate your post!
