The only late model GS/C6Z owners I have known to have scavenge problems were running sticky track tires on a trailered dedicated track car.
GM never required me to preheat the oil in my C6 Z06 but I did witness my buddies brother Jim Herlinger go through a 3 hour ordeal to start his ALMS Pratt&Miller C5R Vette. The guy from Pratt&Miller told him that a different spec motor could be built to allow starts with ambient temprature oil/water temps. That C5R was docked to a pre start cart the likes of which I had only observed being used by the Toyota F-1 team at Laguna Seca.....I don't want to have anything to do with any car that requires the employment of a "Race Engineer" to get it onto the track.

Guys, be careful when selecting your heating elements for these tanks. You have options of wattages, and the higher wattage ones will actually scorch the oil in the tank, and turn it a dark color. I bought a tank for my late model once from Ernie Irvin, and he had a large element in it which scorched mine.
I ran a 15 quart tank, and could safely preheat my oil to 100 degrees. We always did this at the track, for qualifying, and pre-race.
With both corvettes that I've owned, I never got on the car until I saw my oil temp reach 170 degrees, but I'm anal about how to treat a cold engine vs. a warm engine.
