Let's just take an SS... with all my listed mods, I gained around 55 rwhp

Baseline was like 355... now I'm at 410... that's a 15% increase... It "should" be the same here... maybe a hair more so with all that it's mire likely you'll be about 580-600 at the wheels with the pulley... Just cancel out the 15% drive train loss. If you want to talk CRANK hp, youd likely be 670-700 range... so yes if you're talk crank, you'd be right there. You could play with tune a lot and different pulleys. Also a cam and you'd be pushing 800 crank hp easy...

I would do it if I had the bank roll... at the warranty anyhow!
