I have an FE. I have the Canton 7 qt Road Race Pan. I have a custom Cobra like mount for the
oil filter that supports a Fram HP-6 style (BIG) filter which I think holds about 2 quarts. My installation is not complete. I have been running the motor on the frame only without
oil cooler. And have been using about 9 quarts. I also just purchased a Accusump (the 3 qt high pressure). I am going to mount the body soon, and that will allow me to mount the cooler and Accusump and get the line length, etc finalized. I would guess my total system will be:
Pan 7 qts
Filter 2 qts
Cooler 1 qt
Accusump 3 qts
total ~~ 13 qts
Hope this is a help. Once I have the car on the road I will know precisely how much to put in each time, etc.
