Compared to what? Solving world hunger? Easy!

Would be nice to know what you have, what you are intending, and what you'll be using the final product for.

What intake manifold?

I'd add an electric choke kit for a daily driver.

Plan on needing to tune it, both the initial set-up (float levels, idle speed and mixture) and jetting.

I'd start with what it comes with, see how it does. Typically go in 2 jet size increments up or down to get to the final sweet spot.

The Holley jet assortment kit is an easy way to have the jet sizes you're going to need (probably ever), won't cost more than a few jet changes if you bought the jets in pairs.
