550/1680 will get you to 500rwhp running around 45psi static fuel pressure. If you want to make more power you can turn up the fuel pressure or get bigger injs. If you are buying all new inj I would go with a 720/1680 setup.

 

Thanks. I am getting all new so the 720/1680 is where I'll go.



anyone have anything contradicting this?
