ok so your saying bigger jets/smaller or main valve in carb??
No, not bigger jets or power valve changes. Change the accelerator pump nozzles(shooters) to a larger size, and you may possibly also need to put on larger pump cams(the plastic cam that moves the accelerator pump arm when you open the throttle).

This is a Holley carb we are talking about? You said 830 cfm and that is a Holley size, so I just assumed.
