i have a 1985 Eldorado 4.1liter (TBI). its a good car but i want a little more power out of it, something that will make it get up and go, i thought of maybe installing a Carborator on it since all the TBI is is an eletric carb, just not as good. Anybody know if its possible or not?

Not possible without fabricating an intake manifold or modifying the TBI manifold. TBI is just as good as a carburetor for power, assuming both are properly sized for the application.
