Clunking noise when Accellerate Hard

At first, the noise was not that bad, it was a small clinging noise. Someone said it might be bad u joints or something like that.
After a road trip, it got worse. Now when i push down on the gas, its a real loud clunking sound and you can feel the back end shutters real fast. But if im already moving and i push on the gas again, no studder and no clunking.
Does anybody know whats wrong? How dangerous is this and is it expensive?

I have a 92 RS Camaro with 304TBI

Sounds like you have a broken transmission mount.

You can get an Energy Suspension polyurathane one from some place like Jegs for around $23 or so and you won't have to worry about it breaking again, or you can get a cheap auto parts store rubber unit for about $10-$12.

Then pretty much all thats left is the driveshaft & U joints, torque arm & control arms, shocks, antisway bar, and rear axle internals.

Check the condition of each particularly all bushings and mounting points. Don't forget the front torque arm bushing, and the upper shock mount.
There may be damage inside the gear carrier/differential. A quick inspection there may be in order and while in there it would be a good chance to change the axle lube.

You'll have to ask Miss Cleo about that. Without knowing what is actually wrong, who is to say how dangerous it is or isn't.

Best case scenario:
Find the problem then get it fixed if important, or determine that is is really not important or dangerous. No more problem

Worst case scenario:
Just keep driving. Something major in the rear suspension suddenly comes loose. There is no control! You crash into a stationwagon full of Nuns followed by a school bus full of kids and the resulting explosion kills everyone but you, but leaves you a quad for the rest of your life.
