400 sbc block max hp

[4cylpro]

Hello I was wondering if anyone knew the max hp of a 400 sbc block that's bored 30 over? With boost what would be the max hp, not n/a. if that helps anyone. Cause I've seen 383 sbc's hold 820 rwhp with boost. The stock block that is. An since the 400 sbc has a thinner cylinder wall i was wondering if any of you other v8 guys knew. Thanks for the help.

I'm running a bowtie block that started as a 400ci motor but its been built into a serious drag motor. It won't see that 800hp on motor but it will see hopefully over that on the bottle but Ive spared no expense on it.
