Mike, wish I knew more but an FE with a full sump and
oil cooler could need 12 quarts. Add until it registers full, then run motor till warm, let settle and you'll finally know. If your dipstick is correct you do not have to worry about overfill. If it may not be correct, just add
oil to 1 quart down and run, rest, measure. Jeff Classic has a way to eyeball check if your dipstick is marked correctly. How many quarts came out?
