Oil pan Which one? 408!

I called Kevko and they said its 6 quarts in the pan plus 1 quart for the oil filter for a total of 7 quarts.

Yup. I doubt you can use the dipstick readings, that's what the oil level plug is on the side of the pan for. Fill it up the first time and check the level with the plug, then mark it on the dipstick.
