Not a stupid question at all. For ten years I ran five quarts with filter in my 70 GTO w a 400 and never had a problem. Fast forward to 08 and my engine builder, Jack Gaydosh says six quarts with filter on my signature 400. So that's what I've been doing with no issues. Oil line is a little past full on the dipstick. I know it's not a 350 but hopefully it helps.
