I drive my vette every 2 months. I have been pulling the pump relay to crank without starting as a pre-lube to avoid dry starts, between drives. The LS3 has 15K miles/dry sump and gets Penzoil Pure Platinum 5W-30 w/Fram Ultra filter annually.
No need to pull any relays to crank the motor without starting. On the C6, or at least on mine, if you hold the accelerator to the floor before pushing the start button it will crank for 10 seconds without starting, or until you release the clutch. I do this before starting when taking the car out of winter storage.
My Vette will sit from the end of November until early April. When I start after a long shutdown, I will disconnect the injectors and remove the spark plugs. Then I will crank it on the starter for about 30 seconds, reinstall the plugs and connect the injectors and start it up.
