I'd like to remind you that even though those cars have stock bodywork, they can shift weight internally to help keep the car on the ground. So if front lift was an issue, they could place weight up front to counter it. I'm not saying this Camaro did do this, I have no knowledge of that car, but I've been to Bonneville speed week and seen many that did. Some have no radiator and use a water tank onboard. Many had extra weight up front.
Bonneville 2004 pics by me.
Note this Camaro has a tank in the passenger compartment that has two braided hoses connecting to the radiator lower hose area. I believe the radiator has to be in place but does not have to be functioning. I saw one car with an intake cool air duct running right through the core! Engine is set back to aid rear traction which must be poor with no spoiler and narrow tires.
