the short answer is yes plenty above 1100rwhp. The next question is how long will it last.

Yeah people have gotten well over 1000rwhp, but it won't last very long. The said "safe" level is around 550rwhp. A lot of people run them with no problems at 650rwhp. Like JRENIGAR said, I'm only at 529rwhp and I'm worried all the time that it's going to blow lol.

Most aren't true SBE, but massaged using stock parts.

I've been a 780rwhp with a D1SC on a stock bottom end LS3 for a while now. Should be making more soon with my switch to a flex fuel setup and some other stuff.

That's crazy power levels out of stock bottom LS motors, but like others have said, for how long.
