Gunner-this is not euclidean geometry (
)-Pat is being kind here when he says Joe has been known to make a mistake -you'd be a hoople to believe otherwise or you don't know him.
If he ran your engine when he built it for Owner #1, he knew how much to put in it. Then he drains it to ship. He put in what ever dipstick it came with or was on his shelf. Marks like 'add', 'safe', 'full', 'add', 'low', 'oh-oh', only apply to whatever passenger car the stick was in on day one. T-shaped, trap door race pans need calibration beyond 'it was in a '67 T-bird'. If he didn't run it, it went out dry and O #1 began the myth of 11 qts.
Because a pan has a capacity of 9 qts
does not mean it should be run at that capacity.
Only dry sump systems want 11+ qts because the oil's in a
tank- not 2 inches from 6000+RPM. Persist in treating it like a 24 hour endurance race engine and you'll push oil out of gaskets and seals. To say nothing of the power loss dragging the crank through it. 11 is surely above the tray as Pat said. You're only thinking about flat level ground-where does oil that's above the trap doors and cheeks go on a .9G turn? Answer: to
expensive places.
The foolproof way to not hurt you motor is to measure. To do that, remove the pan, clean to perfection, then add
seven qts of water or cool-aid and measure the distance from the fluid to the pan rail top edge. Then, with it mounted in the block, measure the hanging length of the dipstick from the block rail to what ever the fluid level of seven is in the pan.
Re-mark the stick with a file and
that's your correct fill level. File off the other BS marks-now you have a stick that's matched to the pan's correct
operating level.Add the following: Your filter will hold .75Qt (Mobil1, 301) and lines on an ERA hold at most .5qt.
That's all the oil your 446 needs, whether on parade, autocross, road race or drag race duty, 4000 or 8000RPM. If your too lazy to do that-take the advice of several of us
who have the same setup (and have told you repeatedly) and just don't crazy fill past 7.
Rod, this applies to you too-Aviad=10 qts is
what the pan will hold-NOT what it should be dynamically run at. Engine displacement has no dire requirement for over-filled oil sumps.
There's no hero value in telling the sheep 'yeah, that's an 11 qt. pan in there!'
