Clear Flood Mode can also be used as a pre-oiler.

This feature is designed primarily to clear the engine of excess fuel but also cause oil pump to move oil around

To activate, press the accelerator pedal to the floor first and then turn key to start

The engine will crank but will not start, as it clears any excess fuel, and as a pre-oiler before start up by cranking for 10 seconds and resting for 10 seconds,
repeating 2 times.
By doing this, the oil system will be pressurized to 25 psi before you actually start the engine.
This system has been in all Corvettes since 1982 when the cross-fire injection was introduced and is even mentioned in the C8 owner's manual
but should also work with older carb engines
