I would think you could build 1,000hp for much less than some of the other estimates here if you went blown. A natually aspriated motor cost much more to make that much power. You would not need to spend a fortune on heads with a blown motor. Also, with the $700 forged cranks out now, you can save about $1,500 or more over a premium billet too.
