gm rocket block

my friend had picked up an gm rocket block a few years ago

unfinshed bores and lifter bores
bbc cam bearings
400 mains
wet sump
tall deck block
max displacement is 455ci
i can purchase this block for 2,200 bucks , how stong are these gm blocks

reason im asking is i am building a 434ci twin turbo small block to run in x275
it will be 434ci 9.5-1 cr, with cnc afr 227 heads, solid roller cam , single plane efi intake with twin 66mm turbos

this combo is capable of 1000hp plus easy

with this block handle it or should i just buy a little m
