3310 is a vacuum secondaries carb. They can be converted to run a metering block in the back but most of them (and how they are set up stock) use a metering plate for the secondaries. There is no jet changing back there. In the front it should be somewhere around 72s and that’s a good place to begin.
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?
