The 1980 Camaro Z28, like most cars of that era, has a hood release lever located inside the car, usually near the driver's side lower dash area. There's no universal location, so you'll have to look carefully. It might be under the steering column, near the knee bolster, or even tucked away under the dash. It's often a small lever or a pull-tab.
Once you locate and pull the interior release lever, you'll need to go to the front of the car and lift the hood. There's usually a hood latch near the grille, often a small lever or a catch you need to unhook. You may need to apply some force.
