Question about 1983 Pontiac Firebird
It's likely the float sunk in your Quadrajet and fuel is entering your crankcase through the cylinders. The knock may or may not be related. Replacing the float and needle valve and seat will fix the problem.
Another cause may be that you are not getting a complete burn of your fuel (which is a beautiful thing about muscle cars!) and a rich blow-by is entering your crankcase, giving you a fuel smell in your oil. The knock could also be from a poor tune-up, timing too far advanced or low octane fuel. Depending on the knock, it is possible that there is a mechanical problem, but you didn't mention any problems with the way the engine runs.
