I have a 7 quart oil pan on my 408. I called moroso and they said put in 7 plus one for the filter. Talked to the engine builder and he said 7 total. The motor is gonna be revving up to 6500 rpm. I dont want to starve it, but I dont want to over fill it. The motor is a fordstrokers 408. I changed the oil the other day and put 7 total in. There is nothing on the dipstick. I understand that you have to shorten the tube to get an accurate reading. How many quarts do you run in these pans?
