Would the use of a windage tray reduce the effects of an over fill? I would think so. I have often heard of people using an extra quart especially if on a track. Does anyone know how far below the crank the ideal
oil level should be? If so, (let's assume 2" below the crank)with the pan off, install the dip stick and measure down 2" from the crank and mark the spot on the dip stick. Then use the top of the pan as a reference and measure down to that same spot. Add water and see how many quarts it takes to reach that level. Add an extra quart for the filter. You will atleast have a reference point and know where you are on the stick and you can make adjustments as needed to atleast reach the same level each time you fill. I don't think there would be any problems as long as your below the crank. Just my .02 cents, there are smarter engine guys here than me, so take my advice for what it's worth.
