Holley and fresh air?

I was thinkin with the scoop sealed to the hood, I would need the bounce up a few jet sizes? So there's really no way to adjust secondaries on that other than maybe drilling out the built-in Part?
Correct. You can buy different plates I think but I’m not positive on that. You may need to jet up or down depending on your specific combination but I would start with the factory calibration and read the plugs.
