I have a 402 pan on a 71 hp motor. Last time I had it off I did a bunch of fluid level measurements and discovered that 4 quarts was way below the windage tray, and of course this is at static condition, with no oil suspended up top. At 5.5 quarts I. The pan the level was still bellow the belly of the windage tray.

I decided that 6 quarts total (including whatever the filter holds) is not a problem.
