I'd go with heavily modding what you have. The GT500 is way overpriced currently and overweight. In stock form it loses to a stock C6 vette in performance.There are numerous GTs on this forum that are putting down at least the hp that you are looking for, with and without a built engine.

Yep, I'm putting down 443 rwhp, which equal about 520 crank hp. That is pretty much the KB, out of the box tune with 8psi running 92 octane pump gas. Anything more than that and you run a very good chance of a blown engine, from what I have been told. I feel comfortable with my HP rating as I don't believe KB would put out a product (with an out of the box install) that would compromise the engine, thus compromising their reputation and market share.
