Re: 96 Sho
First, pressure wash the underside of the vehicle, then, go to your local auto parts store and add a half ounce or so of UV dye. If you have a trouble light, put in a UV bulb and you should be able to narrow down the source of the leak. I'd drive it 50-60 miles or so. I'm not sure how accessible the SHO engine is to view, but perhaps it's something as simple as a valve cover leak...as the car has 250K.
The leak changing to a slow drip has me believe that it is most likely a gasket problem. As the engine warms, the gaskets tighten up allowing less oil to seep out.
