Your better off to buy a crate LSX and turbo it if your really after 1000hp, E85 and 20lbs of boost should get you there. We have a car in our shop now (corvette) with LSX with 78mm turbo on E85 running on 20lbs of boost it laid down 863hp to the tires. I don't know how healthy your budget is for making this 1000hp but to have a reliable 1000hp vehicle is going to take at least 15K and that's if your doing most the work yourself.
This is very true; a reliable and street-able 1000 hp is no small or cheap task.
