I've seen a 572cid crate engine in a 4th gen if it was done a 8.1L can be done it has all the same external dimensions. It has the engine old style engine mount bolt pattern and the same bell housing bolt pattern. Check out the truck section similar subjects have come up lately.

That is going to be one nose-heavy car. But a brute.

I know BMR makes some K-members for SBC/BBC swaps
into 3rd gens, dunno if they have stepped up for 4th
gens yet.

I know that someone put one in a C5. When it was all said and done it cost more that a 427 LS1 and made less power. Not sure what the point of it was
