Is there any special procedure for checking engine oil specific to the Z06 LS7?

A cut/paste from the '07 owners manual pdf:
Checking Engine Oil (Z06 Only) It is a good idea to check the engine oil level every time you get fuel. In order to get an accurate reading, the oil must be warm and the vehicle must be on level ground. The engine oil dipstick handle is a yellow loop. The dipstick is located on the dry sump engine oil tank. See Engine Compartment Overview on page 328 for the location of the dry sump engine oil tank. Z06 models have a racetrack-ready dry sump engine lubrication system. This high-performance system operates differently than a standard engine lubrication system and requires a special procedure when checking the engine oil level. Follow this procedure closely when checking the engine oil level. The engine oil level must be checked when the engine is warm. Cold oil level in the dry sump tank may not indicate the actual amount of oil in the system. With this system, engine oil is contained in an external tank, separate from the engine. Under normal operating conditions, the oil pan under the engine does not store any oil. If the vehicle has been parked for an extended period without the engine being started, some oil will seep back into the oil pan, reducing the amount of oil held in the dry sump tank and there could be no engine oil at all showing on the dipstick. This is normal since the dipstick is designed to read engine oil level only after the engine has run long enough to reach normal operating temperature. Do not add engine oil based on cold engine dipstick readings. The engine oil level on the dipstick will also be inaccurate if checked while the engine is running. 1. To obtain an accurate engine oil level reading, warm up the engine to at least 175°F (80°C). Cold oil will not give a correct oil level reading. 2. Once the engine is warm, turn off the engine. Checking the oil while the engine is running will result in an incorrect oil level reading. 3. Wait at least five minutes (but not more than 20 minutes) to allow oil to drain and settle in the engine. 4. Remove the dipstick from the external engine oil tank and clean it with a lint-free paper towel or a cloth. Re-insert the dipstick into the external oil tank, pushing it all the way in until it stops. 5. Remove the dipstick from the oil tank and read the level on the cross-hatched area. Oil levels that fall in the cross-hatched area are normal. When to Add Engine Oil (Z06 Only) If the oil is below the cross-hatched area at the tip of the dipstick, you will need to add at least one quart/liter of oil through the oil fill cap opening in the oil tank. But you must use the right kind. This section explains what kind of oil to use. For engine oil crankcase capacity, see Capacities and Specifications on page 427. See Racing or Other Competitive Driving on page 290 for additional information on engine oil. Notice: Do not add too much oil. If the engine has so much oil that the oil level gets above the cross-hatched area that shows the proper operating range, the engine could be damaged. See Engine Compartment Overview on page 328 for the location of the external engine oil tank and fill cap. Be sure to add enough oil to put the level somewhere in the proper operating range. Push the dipstick all the way back into the oil tank when you are through.

Thanks, Chewey. It belongs to a friend and I'm co-driving with him. He is not very mechanical so I figure I'll have to take the lead on making sure the car is serviced correctly.
It's a good opportunity for me to see how the car does without going out and tying up $70,000. My impression is that the car is not bad for open track or fast autocross courses, but the steering is too slow and the wheel base too long for a more typical tight course.

just disconnect the front anti sway bar for tight courses and the turn in will open your eyes. some clubs set up their courses so the smaller cars can win FTD but with the front bar disconnected you will surprise them.DO NOT try this on a fast course.

I've set FTD several times with the car already. I don't think your idea would work except for the tightest parking lot course. I drove a car with in excess of 550 hp that had been set up that way (actually set up for drag racing) and it was undriveable. Throttle on oversteer was unmanageable.
I can't do anything about the steering or the wheel base, but with the right balance, you can pitch the car around corners and still catch it on corner exit. I'm just about there, now.
Thanks for trying to help, though.
