Revving up from under the hood

Stupid question, but I really don't want to get hurt.

I'm gonna make a youtube vid tomorrow of my LT1 swap in my Caprice, and want to rev up the engine while holding the camera over the engine.. so obviously i need to rev from under the hood..

i know the silver piece is the throttle, with the springs and wire, but how do I move it to make it rev up?

it only moves in one direction from idle.

Just be safe and get someone to sit in the car and rev it.

Well, here's the vid.

Pitty I didn't rev high, those nervs kicked in.. Stupid fear I got I guess.

Cool.

sounds good
