I have an '84 z28, and basically whenever i accelerate i hear sort of a hissing noise coming from the front end of my car and can't pin point it, when i take my foot off the gas the noise dissipates. I'm not sure if it would be a belt or something else and if someone could let me know what they think that would be great. P.S it does not sound like fluid escaping.

Sounds kinda like your cat has busted up inside and is now blocked, and maybe one of the AIR check valves has blow out as a result.

Don't drive it like that, really bad strange things can happen.

Park the car and pop the hood, and have your assistant put the car in gear and their foot on the brake and give it gas LIGHTLY, and see if you can pinpoint the source.

I dont think it would be the catalytic converter but here's an interesting video of a third gen that had a catalytic converter issue.
Does it do the hiss at a dead stop when given gas or just when driving?

It only sounds when i give it some gas. When i take my foot off the gas it goes away.

Great video by the way, my car does not sound anything like that but i am going to be very cautious when running the car, i am almost positive its a belt by the way it sounds. Thanks for the advise

No problem, but I suggest having someone look under the hood as you are lightly reviving it to help pinpoint the issue, as stupid as this sounds, maybe a little water on the belt as it is running?

By that i mean pour a bit onto the belt and see of the sound starts to go away
