On my 86, it connects to the exhaust manifold on top near the back. Congrats on the 383.

Dude, That's AIR not EGR! Did you keep the AIR Pump and Valves? If so, the AIR Pump feeds the first valve that ports under ECM control to the second valve or overboard to the little muffler tube. The second valve ports, again under ECM control, to the Exhaust Manifolds or the CAT. So the CAT tube should connect to the open port on the second AIR Valve.
