500hp 5.7? Whats it take?

I'm just trying to get something going somewhat on the cheap right now. I've been building this car for 7 years now. A few weeks ago I was going to sell everything off and be done. Now I've sold off most of my big block stuff because I just couldn't afford to finish it and it was too radical for a street car for what I want to do. Seems most of this new gen stuff is pretty reasonable. I'll probably just go with the 05 for now and get as much as I can out of it and then slowly build an eagle headed motor while I enjoy this. I'd like to get in the low 11's with this motor, car should be about 2800lbs hopefully, th400 and an 8.8 rear end with a spool.
