What do I need to do to build a 1000hp turbo small block

I would maybe start with a stroker motor to around 408. No replacement for displacement. And a super strong block. I usually build big blocks, and I hear that when you get above 700 horsepower, you start to have block problems. Like separation of the block near the cam area. May not be true for the stronger blocks such as the 230. From there, build a Hi Output motor, roller cam, Trick Flow heads, etc. Then boost it. There is a thread on here of a small block pushing 700 plus horsepower. Check it out. Without supercharging!
Thanks for your reply
I've read some threads on here about boosted small blocks but haven't seen the one called without supercharging. Thanks I'll look it up.
What is the 230 block
Is that an aftermarket made block
