Steve...Like I told you before, I'm very sorry for what you've gone through, but you're better off sitting on it and having it fixed by someone professional when you have the financial means to do so.
I'd suggest Dwayne Porter at Porter Racing Heads or Todd Marsh at Marsh Performance.

I'm pretty sure Tig's 600+ inch motor that Todd Marsh built for him made well over 1000 hp on pump gas.
I don't see it as impossible at all. My 572 hemi is pretty mild and makes over 800 hp N/A on pump 93 (140 mph at 3800+ lbs.). With a much more aggressive cam, bigger heads, and a tunnelram w/ a pair of dominators...I feel pretty confident it could make 4 digit power. I decided to leave the motor mild and spray it into 4 digit territory. My last outing proved it to be making around 1080 hp w/ a very mild tune up.
