I don't recommend flooding the engine, that's one of the few ways (only way?) Seafoam can cause any damage to an engine. Suck up too much at once and you risk hydrolock.

My reading suggests the following method:

Add half a can to the gas tank, slowly suck up the other half using a vacuum line (being careful not to kill the engine), and then shut off the car and let it sit 10-20 minutes. Start the car again and rev it up for a few minutes, and then take it for a drive, being generous with the throttle. Some say to put Seafoam in your oil at the start too, but I don't trust it. An oil change is recommended after Seafoaming.
