I need to get pics of the crank to block height difference, the crank only hangs below the bottom of the block maybe 3/4." Which from looking at the pics on pg 1 is well above the oil level with even 7 quarts!

SOHC iron block identical to the aluminum DOHC that I have sitting across the garage, just didnt want to unwrap the new shortblock until Im ready to assemble it. Atleast this will show what Im talking about and maybe add a nod in favor of the arguement for 7 qts.
There is another pic in this thread:

Great thread! Lots of interesting info:read:
ttt mofos! this is a great thread. every 4v owner should see this! Chad (01qwickcobra) FTW!:rockon:
Gotta love some opposition. Actually, I really do like this thread. I used to run 6.5 qt.
So with the crank sitting about 3/4" below the block, I can see that there is a chance that the crank will hit the oil with 7 qt...
-- If the car isn't on perfectly level ground.
-- And only for the first few revolutions after starting the engine before the oil pump starts to lower the level while it distributes the slick stuff like it's supposed to.
I guess if you're into reving the engine & dropping the clutch before your right hand comes off the key, you might generate some foam. I recommend 6 qts for you then -- among other things.
7 qt for rod bearing longevity here.

Well said, I run 6.5 to 7.
7 quarts. 106K. Beaten Daily with no issues.
Works for me.

1. You realize that the picture with 4 quarts in the pan is probably the situation when the car is running right. Although you may possibly get some sort of windage if you are on a steep decline, id consider it pretty minor.
2.the filter and oil cooler keep about 1 quart in them combined, reducing the level in the pan to 6 quarts on start up, which still should not cause an issue. even so, it would occur for maybe 25 seconds at start up, where rpm is pretty minimal.
SOme good info here.
I have been thinking about the fact that the turbos add extra heat to the oil as the oil cools them. Also, the fact that there is some oil suspended in the feed lines, drain lines, and turbos. So, I will now be running 7.5 quarts.

exactly! that pan is only full for two seconds after the car is started. so probably only 3 quarts are in the pan most of the time anyway:-D
The picture with the oil at 7 quarts is with the top of the oil pan level. If I remember correctly, the engine and oil pan are on about a 3-6 degree angle (down) towards the rear of the car. How will that affect the amount of oil where the oil pickup tube is? Also, that would mean that the counterweights of the crank that are towards the tranny would be touching the oil, correct?

no.
The engine is typically at a negative 4 degree angle, and the cobra has a windage tray towards the rear of the motor (front two counterweights exposed).
Once again, keep in mind that there are more like 4 quarts in the pan when the engine is running (.75 in filter, .25 in cooler, 1.5 in the heads, and .25 in the pick up, and .25 in teh block passages ) and the neg. angle will only help as the pick up is in the sump.

Can we sticky this already!!
Thats what I had to put in my car for it to read full on the dipstick...but thats with a canton 7 qt. pan.
you must have been very bored
It's included in the subforum thread I sent to Sid. It'll either be stickied or moved to the subforum soon. :beer:
Coolness. Thank you!
back from the dead.
how come the 03-04 Cobra guys arent spinning bearings with the vast majority runing 6 qts?
