I was thinking about getting a 5.3 block and using Callis 383 rotating assembly and boosting it to 900 to 1000hp. Can the 5.3 iron block handle this?
I have a ls1 block but I dont think it will last very long at this power level. I know the 6.0 block will handle this but 5.3 blocks are cheap and this is a cheap 1000hp budget build...lol

well 346ci would be harder to make the 1k, and spool up will be a bit slower. I had a buddy with a ls1 383 with around 800hp and was fine and is still running good, so maybe just use the ls1 with a 4inch crank and boost it, but I kinda want iron block tho for peace of mind...lol
