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

I’ve never built a sbm to failure but I was planning a 700 hp build two years ago. I saw enough evidence on here to convince me that my block wouldn’t live long at that power level. I then talked to two reputable builders and both said the limit for a sbm is right around 600/650.

Everyone has their opinions and it’s the same with the big blocks. They argue it all the time. For an NA or nitrous combo, the threshold is lower than with a turbo combo so those comparisons don’t translate directly. Obviously the R3 block would be preferable but a turbo sbm with some steel caps and a short fill would live at 800whp. Staying stock stroke would be even better. Just my opinion.
