If you were my son I'd say look at getting a running 5.2 magnum or 5.7 from a truck and mate it with an older 904 trans so everything fits in the trans tunnel. Get a 4 barrel manifold for the Magnum. That combo would easily be more power than a typical, streetable hopped up 6
Or........
put a turbo on the /6.and be different There are plenty of posts on this list to research. Think Pishta Pipe.
