If the ticking sound is faint, it might be a bad plug wire (coil wire, coil, etc) shorting to some metal part of the engine/car. Put the car in the garage, close the door and put towels over the windows. Start up the car and then turn all the lights off. Look around all of the plug wires to see if they are "sparking". Also check any wires that run parallel to each other (and are close to each other) for any distance.

I am assuming that the ticking noise speeds up as the RPM's increase. Yes? No?

"I noticed that when I installed my windshield and hood I now here a multiple ticking sound coming from the trans tunnel area."

I would assume that you have ruled out the hood and windshield as the source of the ticking noise. If not, put some pressure on the hood and windshield and see if the ticking volume or speed changes.

PS Edit - the engine is really not under a load if you are revving the engine in the driveway. Do you hear the noise when driving the Cobra? or just in the garage/driveway when its not moving?
