7 quarts in a stock GT pan
Some of you may remember our recent discussion on oil pan capacities. In that discussion I had mentioned that I run 7 quarts in a stock GT pan. I also quoted a former Ford tech that had stated "I suggest you add 1 qt. Adding 1 qt does not over fill the pan to the point that the crank or rods run thru it. When at idle, you're 2 qts low anyways."
Below you will see a pic of a stock GT/Cobra pan with 6 quarts in it. Knowing that the oil filter holds ~ 1/2 quart and even a full quart in this large surface area will only raise the level slightly I decided that 7 quarts was best for me. Discuss please.

i run a little over 5 as the turbo system gives me a bigger capacity. if the pickup tube is fully submerged with the amount that its called for i dont see the purpose in adding more oil than is called for. and that oil sits like that apart on the floor, ever think about what it looks like full throttle and momentum moving it more to the back of the pan?

The pan is 2 quarts low at idle. How low do you think it is at WOT? Maybe I should post the whole quote from the Ford tech. That may answer some questions.
"When at Ford, we ran with clear pans, windowed front covers and cam covers. The oil under high rpms gets slowed in the heads, the front cover and the front of the oil pan.
Front cover?? Oil pan??
As the chain drives the cam system, the oil is trying to get down thru the cover area. Also the area around the front of the pan shares space with the oil pump and pickup tube. Oil is tryig to get back to the pan and everything is in the way.
The drain back holes are the same between 2v, 3v and 4v.
Ford conducts a WOT test for 100's of hours.
On the street you don't see consistent 6,500+ runs. On the track, I suggest you add 1 qt. Adding 1 qt does not over fill the pan to the point that the crank or rods run thru it. When at idle, you're 2 qts low anyways."

i just cant see drain back being so horrible that is can starve 5-6 quarts of oil away from the pickup. also that 6 quarts in the picture is probably cold so 7 quarts at full oil temp is in my opinion cutting it a little close.
