is the 350 a Chevy or a Pontiac? What intake manifold is on the engine now? Do you have a shaker hood that you want to retain?

The intake will accept either carb, and as long as you dont need to worry about shaker then I don't think there's an issue a shorter air cleaner couldn't fix.

If your quadrajet is tuned for your combo though I don't think the holley is going to do any better.

Also 850 is a lot of carb for a 350 moto I would get the q-jet tuned by a true Pontiac mechanic (vs a Chevy guy) and stick with that
